Currently in the `bip158` module we do a bunch of dynamic dispatch using
the reader/writer objects. We can improve runtime performance, at the
cost of compile time, by using generics instead of dynamic dispatch.
The function `match_all` takes an iterator, it does not need to use the
`Seek` trait, we can just pass in the content as a slice, no need to
wrap it in a `Cursor`.

b6c5fc3622 Remove MAX_SEQUENCE const (Tobin C. Harding)
Pull request description:
This is follow up work to the recent addition of the `Sequence` type. We
do not need to keep a public integer const for `MAX_SEQUENCE` because we
offer the `Sequenc::MAX` associated type.
Use the all-bits-set u64 directly in the associated type `Sequence::MAX`.

We are no using `non_exhaustive` on any error types unless we are
_really_ sure there will be no additional variants required.
There are only three error enums that do not have it in the codebase as
of this commit, add it to all three.

The `bip143::SigHashCache` is deprecated in favour of
`sighash::SighashCache` however we still use it in `bip143` unit tests.
Use the new `sighash::SighashCache` in `bip143` unit tests.
We have a bunch of unit tests that verify the BIP 143 test vectors.
Three of these use the deprecated `SighashComponents` struct. We should
implement these tests using the new `SighashCache`. In order to do so we
have to move the tests to the `sighash` module so they can get access to
the private `segwit_cache()` function, and verify the cache internal
state against the test vectors.
Re-write the BIP 143 test vector code using `SighashCache` and remove
the versions using `SighashComponents`.
Done in preparation for removing the deprecated `SighashComponents`.

Pull request description:
[Turns out](https://github.com/rust-lang/rust-clippy/issues/9248) by default clippy does not lint certain parts of the public API.
Specifically, by setting `avoid-breaking-exported-api = false` we can get clippy to lint the public API for various things including
`wrong_self_convention`.
This means the saga of to/into/as continues ... we have used the wrong from for many of our `to_*` methods, they should consme `self`. Patch 1 fixes them. Patch 2 adds an `allow`. Patch 3 fixes a few error enum variant identifiers (removes `Error` suffix).

Error variants should not end with the same identifier as the enum,
i.e., they should not stutter.
Found by clippy after setting:
avoid-breaking-exported-api = false
Clippy gives a warning about `wrong_self_convention` because we consume
self in a method called `is_*`. We have to consume self because the
object has a generic `E` (error type) that does not implement `Copy`.

This commit does two things:
1) BUG FIX: We should have checked that the length of the branch is 1
before computing the spend_info on it. This was introduced in #936, but
slipped past my review :(
2) Update the return type to return the consumed `self` value. This
function can only error when there the tree building is not complete.
Returning TaprootBuilderError causes issues in downstream projects that
need to deal with error cases which cannot happen in this function
405be52f5c Impl string conversion traits for `CommandString` (Martin Habovstiak)

c39bc3909d Extend `ParseIntError` to carry more context (Martin Habovstiak)
Pull request description:
When debugging parsing errors it's very useful to know some context:

from `core` doesn't contain this information.
In this commit a custom `ParseIntError` type is crated that carries the
one from `core` as well as additional information. Its `Display`
implementation displays this additional information as a well-formed
English sentence to aid users with understanding the problem. A helper
function parses any integer type from common string types returning the
new `ParseIntError` type on error.
To clean up the error code a bit some new macros are added and used.

Recently we introduced SPDX license ids but there was some confusion
about the use, form, and purpose of lines before (library name, author).
It was pointed out to me by Andrew that if/when folks cut'n'paste our
code they often will keep the whole blurb. Design it with that in
mind. FTR, Andrew also indicated that he did not mind his name being
removed in favour of "The rust-bitcoin developers".
At first I thought the term "The rust-bitcoin developers" was a bit
wishy-washy but yesterday I realised that I am proud to be part of that
crew, striving to deliver code to the highest possible standard.
Introduce a canonical format for the licences blurb.
- Use the name of the library
- Use "The rust-bitcoin developers"
- Use the SPDX ID

`Sequence` didn't have `FromStr` nor `TryFrom<{stringly type}>`
implemented by accident. This moves a macro for implementing them from
`locktime` module to the `parse` module, renames it for clarity and uses
it to implement parsing for `Sequence`.

1390ee12ec Add a max scriptnum constant (Tobin C. Harding)
Pull request description:
Implement a `LockTime` type that adds support for lock time values based on nLockTime and OP_CHECKLOCKTIMEVERIFY.
For example usage in `rust-miniscript` please see https://github.com/rust-bitcoin/rust-miniscript/pull/408.
### Notes:
I probably should have opened a new PR, this is a total re-write and very different from what is being discussed below, sorry, my bad.
This is just half of the 'timelock' story, its the easier half. The reason I switched terminology from timelock to locktime is that we have to compare two u32s so it does not make sense to call them _both_ timelocks.
If I have missed, or apparently ignored, anything you said reviewers please accept my apology in advance, it was not intentional. The thread of discussion is long and this topic is complex. Please do restate your views liberally :)
Here is a useful blog post I used while touching up on timelock specifics: https://medium.com/summa-technology/bitcoins-time-locks-27e0c362d7a1. It links to all the relevant bips too.

Add a `LockTime` type to hold the nLockTime `u32` value. Use it in
`Transaction` for `lock_time` instead of a `u32`. Make it public so this
new type can be used by rust-miniscript and other downstream projects.
Add a `PackedLockTime` type that wraps a raw `u32` and derives `Ord`,
this type is for wrapping a consensus lock time value for nesting in
types that would like to derive `Ord`.
Integers within Script can have a maximum value of 2^31 (i.e., they are
signed) but we (miniscript) often uses unsigned ints, to facilitate
checking the unsigned type is the correct size to fit in a signed int
add a const `MAX_SCRIPTNUM_VALUE`.

- Remove the separate CI job
