It is possible, although not immediately obvious, that it is possible to
create a `PsbtSigHashType` with a non-standard value.
Add a unit test to show this and also catch any regressions if we
accidental change this logic.
Improve the `PsbtSigHashType` conversion methods by doing:
- Re-name `inner` -> `to_u32` as per Rust convention
- Add `from_u32` method
Note, we explicitly do _not_ use suffix 'consensus' because these
conversion methods make no guarantees about the validity of the
underlying `u32`.
The functions `from_u32_standard` and `from_u32_consensus` smell a bit
like hungarian notation. We can look at the method definition to see
that the methods accept `u32` arguments without mentioning that in the
method names.
Remove `_u32_` from the method names. This brings the `from_*` methods
in line with the `to_standard` method also.
Rust naming conventions stipulate that conversion methods from owned ->
owned for `Copy` types use the naming convention `to_`.
This change makes the function name objectively better, however it makes
no claims of being the 'best' name. We have had much discussion on using
`to_standard` vs `to_u32` but are unable to reach consensus.
We have conversion functions that include suffixes `_consensus`
and `_standard` to make it explicit what guarantees are provided by the
returned `u32` value. The `From` implementation reduces the clarity of
the API.

83dda74ecb Check for SIGHASH_SINGLE bug in writer fn (Tobin Harding)
Pull request description:
Recently we moved the logic for checking for the SIGHASH_SINGLE bug to
the `signature_hash()` function. Although this left users of the
`encode_signing_data_to()` function without correct handling of the bug
there is not much else we can do but alert users to this behaviour.

6ad2902814 Remove feature gated enum variants (Tobin Harding)
Pull request description:
This is the updated version of #874 (which I closed, force pushed, and then was unable to re-open - my bad).
Feature gating enum variants makes code that uses the library brittle while we do not have `non_exhaustive`, we should avoid doing so. Instead we can add a dummy type that is available when the feature is not turned on. Doing so enables the compiler to enforce that we do not create the error type that is feature gated when the feature is not enabled.
Remove the feature gating around `bitcoinconsensus` error enum variants.

Mirror this logic in `SchnorrSigHashType`.
In preparation for constructing an error outside of this module improve
the `SigHashTypeParseError` by doing:
- Make the field public
- Rename the field to `unrecognized` to better describe its usage

This one might be a viewed as code churn or unnecessarily modifying the API, feel free to NACK :)
We have a bunch of methods that use the prefix `get_`, they are not exactly getters because they do more than just access a struct fields so Rust convention relating to getters does not apply, however, the `get_` prefix does not add to the descriptiveness of name hence the shorter form can be used with no loss of clarity.

In this library we specifically do not use rustfmt and tend to favour
terse statements that do not use extra lines unnecessarily. In order to
help new devs understand the style modify code that seems to use an
unnecessary number of lines.
None of these changes should reduce the readability of the code.
Vector initialisation uses neither "Block" nor "Visual" stlye, this is
irregular for no added benefit.
Elect to use "Block" style (as defined by `rustfmt`).
This function uses neither "Block" nor "Visual" style (as defined by
`rustfmt`). This is unusual, code that is regular is less jarring to
read. We tent to use "Block" style for functions so elect to do that
here.
Our usage of `where` statements is not uniform, nor is it inline with
the typical layout suggested by `rustfmt`.
Make an effort to be more uniform with usage of `where` statements.
However, explicitly do _not_ do every usage since sometimes our usage
favours terseness (all on a single line).
We have a few instances of strange indentation:
- Incorrect number of characters
- Usage of neither "Block" style or "View" style (elect to use "Block")
Do various whitespace refactorings, of note:
- Use space around equals e.g., 'since = "blah"'
- Put return/break/continue on separate line
Whitespace only, no logic changes.
When signing a transaction will result in the sighash single bug being
exploitable we should return the 'one array' (equivalent to 1 as a
uint256) as the signature hash.
Add a unit test to verify we return uint256 1 value when use of
SIGHASH_SINGLE is invalid.
