5be1cdb8c7 PsbtSigHashType Display and FromStr implementation (Dr Maxim Orlovsky)
7cdcdaad6c Support SIGHASH_RESERVED in SchnorrSigHashType::from_u8 (Dr Maxim Orlovsky)
Pull request description:
The newly introduced `PsbtSigHashType` uses very different serde formatting from previously used `EcdsaSigHashType`; for instance it does not output human-readable sighash. This is especially obvious when printing out PSBT as JSON/YAML object and is a breaking change from the `0.27`. Serde human-readable implementation requires `Display/FromStr`, which were also absent.

51fef76129 feat: Add Address.is_related_to_pubkey() (Andrew Ahlers)
Pull request description:
## Motivation
This is addressing the second half of this comment: https://github.com/rust-bitcoin/rust-bitcoin/pull/684#issuecomment-1012136845
> but would accept a PR (or two PRs) that returns Result<bool, UnsupportedAddress> and a method to check if a PublicKey is associated with an address.
(The first half was addressed [here](https://github.com/rust-bitcoin/rust-bitcoin/pull/819))
These changes will help build out and improve message signature verification. We don't necessarily need to add it to this crate but it allows for easy verification with something such as:
1. recovering a pubkey
2. checking if that pubkey relates to the given address
## Possible Improvements
- There is likely a better name than `is_related_to_secp256k1_key()`
- This could drop the `secp256k1` part of the name and take in a Pubkey enum that also supports Schnorr pubkeys and then this could be used for taproot addresses as well. This felt like a much larger change that will likely get turned down. Verifying taproot is simple enough and if absolutely desired, similar functions can be added for schnorr keys (tweaked and untweaked)

e27f8ff594 TapTree iterator implementation (Dr Maxim Orlovsky)
Pull request description:
Implemented after @sanket1729 suggestion in https://github.com/rust-bitcoin/rust-bitcoin/issues/895#issuecomment-1074366108
Iterates all scripts present in TapTree in DFS order returning `(depth, script)` pairs.
I propose to have it as an RC fix since this functionality is really lacking and may be required for many wallets working with Taproot PSBT even outside of the scope where I originally needed it (OP_RETURN tweaks for TapTree described in #895)

This PR has evolved into a full blown clean up of the conversion methods for all three sighash types based on the discussion below.
Everything is split up into very small patches to aid review (and bikeshedding, this PR is almost totally just naming things).
EDIT: I'm not convinced this should be an RC-fix, the changes are too wide spread now. It started as just a single method rename. Leaving label as is for others to consider.

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.

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.

In preparation for constructing an error outside of this module improve

- Rename the field to `unrecognized` to better describe its usage
