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

StreamReader before this commit is trying to repeatedly parse big object like
blocks at every read, causing useless overhead.
consensus_encode deal with partial data by simply blocking.
After this changes it doesn't look what remain of the StreamReader is really giving
value, so it's deprecated

106acdc3ac Add fuzzing for Witness struct (Riccardo Casatta)
2fd0125bfa Introduce Witness struct mainly to improve ser/de performance while keeping most usability. (Riccardo Casatta)
Pull request description:
At the moment the Witness struct is `Vec<Vec<u8>>`, the vec inside a vec cause a lot of allocations, specifically:
- empty witness -> 1 allocation, while an empty vec doesn't allocate, the outer vec is not empty
- witness with n elements -> n+1 allocations
The proposed Witness struct contains the serialized format of the witness. This reduces the allocations to:
- empty witness -> 0 allocations
- witness with n elements -> 1 allocation for most common cases (you don't know how many bytes is long the entire witness beforehand, thus you need to estimate a good value, not too big to avoid wasting space and not too low to avoid vector reallocation, I used 128 since it covers about 80% of cases on mainnet)
The inconvenience is having slightly less comfortable access to the witness, but the iterator is efficient (no allocations) and you can always collect the iteration to have a Vec of slices. If you collect the iteration you end up doing allocation anyway, but the rationale is that it is an operation you need to do rarely while ser/de is done much more often.
I had to add a bigger block to better see the improvement (ae860247e191e2136d7c87382f78c96e0908d700), these are the results of the benches on my machine:

With an increased performance to deserialize a block of about 21% and to serialize a block of about 16% (seems even higher than expected, need to do more tests to confirm, I'll appreciate tests results from reviewers)

2959e04ebd Allow specifing a raw `TapLeafHash` in sighash computation (Alekos Filini)
Pull request description:
Still need to add some tests but the code should be ready for review. Please let me know if you have better ideas for the enum naming.
---
Instead of always requiring the full raw script and leaf version, allow
just specifying a raw leaf hash to the sighash computation functions.
This is very useful when dealing with PSBTs, because the
`PSBT_IN_TAP_BIP32_DERIVATION` field only maps a public key to a leaf
hash, so a signer could just take it and produce a signature with it
rathern than having to jump through hoops to recover the full raw
script.

Witness struct is in place of the Vec<Vec<u8>> we have before this commit.
from_vec() and to_vec() methods are provided to switch between this type and Vec<Vec<u8>>
Moreover, implementation of Default, Iterator and others allows to have similar behaviour but
using a single Vec prevent many allocations during deserialization which in turns results in
better performance, even 20% better perfomance on recent block.
last() and second_to_last() allows to access respective element without going through costly Vec
transformation

There is no reason to force users to use a particular format or case for `Denomination` strings. Users may wish to write any of the following and all seem reasonable
- 100 sats
- 100 sat
- 100 SAT
The same goes for various other `Denomination`s.
- Patch 1 enables usage of "sats", "sat", "bit", "bits"
- Patch 2 enables usage of various lower/uper case formatting
