The `TaprootMerkleBranch` contains a vector of `TapNodeHash`s, as such
it can trivially be constructed from an array of the same type.
Implement `From` for all array sizes 1 - 128 inclusive.
"Sighash" is a technical term that newbies in Bitcoin may not know and
could get lost when trying to find how to sign a transaction. This
change attempts to make it more obvious that this module is needed for
signing.

bb612fdafa Set rustv_1_53 in build script (Tobin C. Harding)
Pull request description:
The rust version is supposed to be set by the build script so that users automagically get features matching the toolchain in use. Currently we have a feature in the manifest for `rustv_1_53` instead setting a compiler conditional configuration option in the build script. This causes `cargo +1.41.1 --all-features check` to fail.

I don't see `rustv_1_46` used anywhere, do we need that still?

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.
Recently we merged `commit 53d4fe66b57c255086def2b5e47afaddee776b75` to
fix CI even though a better approach is to use `'_` because it assists
reading the code (shows that the bit stream writer is not writing from a
reference since its writing a `Copy` type `n`).
Add back in the `'_` (I forget what its called).

From BIP143:
> If sighash type is SINGLE and the input index is smaller than the number of outputs, hashOutputs is the double SHA256 of the output amount with scriptPubKey of the same index as the input;
Currently we are using a `Sighash` which wraps double sha256 so while technically correct this means we are relying on `Sighash` to implement `Encodable`. We can remove this requirement by directly using the `sha256d::Hash` type to hash the outputs data.
