32d2d62e0f Rename from_slice methods to decode (Tobin C. Harding)
Pull request description:
The `TaprootMerkleBranch` and `ControlBlock` both have methods on them called `from_slice` but these methods do more that just basic copy from a slice. `decode` is a more descriptive name.
Deprecate the `from_slice` methods and implement `decode`, on other changes to the logic.

The `script` module is large and unwieldy.
Refactor the `script` module, splitting it up into a tree of modules.
Here are a few of the changes and their stated benefits
- Split the two script types out into separate files: Readers of the
methods can then tell immediately from the file name which type they are
reading.
- Put all the impls for the two script types together: Makes parsing the
API easier because one can more quickly see which traits are implemented
on what i.e., all the `AsRef` imlps are grouped together.
- Put the impls for the two script types in order, first `Script` then
`ScriptBuf`: Makes it easier for us to see if we missed something.
- Put the `Builder` and `Instruction` (and associated) types in their
own modules: Some devs find long files hard to navigate, so far there
hasn't been too much push back against short files.
- Put tests in a separate file: This idea was recently discussed.
This is only moving code and fixing import statements etc. No other
changes to the code.
The `TaprootMerkleBranch` and `ControlBlock` both have methods on them
called `from_slice` but these methods do more that just basic copy from
a slice. `decode` is a more descriptive name.
Deprecate the `from_slice` methods and implement `decode`, on other
changes to the logic.

It may be useful to access the transaction stored in `SighashCache`
during signing or afterwards, especially when the transaction is stored
without indirection (to enable long-lived storage).
This change adds the appropriate accessors.
The requirement for a type dereferencing to `Transaction` prevented
storing the cache in long-lived data without resorting to silly
wrappers. Since `Borrow` is implemented both for `T` and for smart
pointers it's a more flexible bound which this change implements.
While this is technically breaking, all usual non-generic code will
continue to work beause smart pointers generally have `Borrow`
implemented.

Pull request description:
This work started out, as the branch name suggests, as an effort to use the `hex_lit` crate. But once I got to this stage it seems that the `hex!` macro we have provides different, useful, functionality than the `hex_lit::hex!` macro (it allows usage with non-consts). So I'm unsure if we want to remove it now.
- Patches 1 - 6 are preparatory clean ups
- Patch 7 reduces usage of `FromHex`, please see git log for full description
- Patch 8 removes `hex_from_slice` and fixes a bug in how we display `Sighash`

`Sighash` should be displayed forwards according to BIP143. Currently we
are displaying it backwards (as we do for double SHA256). This is
working because parse using `Vec::from_hex`.
We have the means to parse hex strings directly for hashes, we no longer
need `hex_from_slice`.
BIP143 test vectors display double SHA256 forwards but we display
backwards, this is acceptable because there is no fixed display in the
ecosystem for double SHA256 hashes. In order to overcome this we parse
test vector hex strings with into `Vec` when needed.
Remove `FromHex` from hash and script types
- Remove the `FromHex` implementation from hash types and `ScriptBuf`
- Remove the `FromStr` implementation from `ScriptBuf` because it does not
roundtrip with `Display`.
- Implement a method `from_hex` on `ScriptBuf`.
- Implement `FromStr` on hash types using a fixed size array.
This leaves `FromHex` implementations only on `Vec` and fixed size arrays.
In preparation for modifying some unit test data structures, manually
format the code so it is uniform.
Move elements added to a vec with `vec!` onto a new line so they all
line up and one can better see what fields go where.
Refactor only, no logic changes.
It is easier to maintain code if macros use the fully qualified path to
types and functions instead of relying on code that uses the macro to
import said type or function.
We have old Rust 1.29 error handling code still in `hashes`. Implement
`std::error::Error` for the `hex::Error` and `error::Error` types in
line with "modern" Rust 1.41.1 error handling.

The `rustfmt` config option `required_version` causes grief in CI
because everytime `rustfmt` is update our `nightly` job fails. Since we
require nightly anyways to run `rustfmt` the config option is basically
redundant.
