a6e8f581db PSBT BIP32 keys moved to Secp256k1 from bitcoin ECDSA (Dr Maxim Orlovsky)
Pull request description:
Fourth step in implementation of Schnorr key support after #588. This PR is a follow-up to non-API breaking #589 and API-breaking #590, which must be reviewed and merged first. ~~(The current PR includes all commits from #589 and #590, which should be reviewed there.

UPDATE: All related PRs are merged now and this PR is ready for the review
PR description:
While PSBT BIP174 does not specify whether uncompressed keys are supported in BIP32-related fields, from BIP32 it follows that it is impossible to use uncompressed keys within the extended keys. This PR fixes this situation and is a companion to BIP174 PR clarifying key serialization: https://github.com/bitcoin/bips/pull/1100

I think it is more natural to write Wintess::new() followed by Witness::push()
then Witness::default(). In any case, there is no harm in having additional constructors.

Pull request description:
This is third step required to introduce Schnorr key support according to #588. This PR starts API-breaking changes and is follow-up to non-API breaking #589, which is already merged.
PR rationale: BIP32 does not support uncompressed keys and using type with compression flag was a mistake

Pull request description:
The original `LeafVersion` implementation was just a newtype around `u8`. I think that having enum explicitly listing consensus script implementation rules may be more beneficial in terms of both code readibility and future use of multiple script types, where `LeafVersion` may operate as a context object provided to `Script` to specify interpretation rules for particular op codes.

Pull request description:
In the first two commits I moved some data from source files to the newly introduced `test_data` dir, including it with `include_[str|bytes]!` macro.
The second-to-last commit introduces a big block in test_data which is very handy in ser/de benchmark (I used it for #672) because with smaller blocks you may not notice performance improvements.
Since I don't want to pollute the package the last commit excludes the `test_data` dir from the published package. I think it's fine to do it because dependent packages don't run dependencies tests.

533120899e Put rustdocs above attributes (Tobin Harding)
Pull request description:
(Trivial / Very low priority PR)
Rust idiomatic style is to put the rustdoc _above_ any attributes on types, functions, etc.
Audit the codebase and move comments/attributes to the correct place. Add a trailing full stop at times to neaten things up a little extra.

9ca6c75b18 Bench StreamReader (Riccardo Casatta)
Pull request description:
`StreamReader` performance is extremely poor in case the object decoded is "big enough" for example a full Block.
In the common case, the buffer is 64k, so to successfully parse a 1MB block 16 decode attempts are made.
Even if a user increases the buffer size, `read` is not going to necessarily fill the buffer, as stated in the doc https://doc.rust-lang.org/stable/std/io/trait.Read.html#tymethod.read. In my tests, the reads are 64kB even with a 1MB buffer.
I think this is the root issue of the performance issue found in electrs in https://github.com/romanz/electrs/issues/547 and they now have decided to decode the TCP stream with their own code in cd0531b8b7 and 05e0221b8e.
Using directly `consensus_encode` seems to make more sense (taking care of using `BufRead` if necessary) so the `StreamReader` is deprecated
