Calvin Kim 31fc1f8638 Add support for sha512/256
Adds a new file named sha512_256.rs that implements the sha512/256
hash. This was needed as a part of
https://github.com/rust-bitcoin/rust-bitcoin/discussions/1318 to
drop the sha2 dependency in current rustreexo code.

Tobin C. Harding b7a84d0c68 hashes: Do not implement Deref
Currently we implement `Deref` for hashes. From the docs [0]

 > Deref should only be implemented for smart pointers to avoid confusion

Furthermore because we implement `Deref` as well as implement
`internals::hex::display::DisplayHex` for slices hashes get coerced into
slices and `to_lower_hex_string` can be called on them, this is
incorrect because `DisplayHex` does not account for hashes that display
backwards so we end up with the wrong string.

Tobin C. Harding 5a2a37d4be Allow dead_code/unused_imports when fuzzing
Littering the codebase with `#[cfg(not(fuzzing))]` is a bit messy just
to quieten the linter during fuzzing. Instead just globally allow.

Calvin Kim 15b5af1117 Export sha512::HashEngine fields/function within the crate
The export is for the sha512/256 implementation as it can use the
existing HashEngine in sha512 and avoid code duplication.

Tobin C. Harding 9674bf29fe hashes: Fix clippy warnings
Recently clippy was updated and now new warnings are generated for the
`hashes` crate.

Clippy emits 3 warnings of form:

 warning: this expression borrows a value the compiler would automatically borrow

As suggested, remove the explicit borrow.

Tobin C. Harding b9643bf3e9 Import bitcoin_hashes crate into hashes
We would like to bring the `bitcoin_hashes` crate into the
`rust-bitcoin` repository.

Import `bitcoin_hashes` into `rust-bitocin/hashes`, doing so looses all
the commit history from the original crate but if we archive the
original repository then the history will be preserved. We maintain the
same version number obviously and in the changelog we note the change of
repository.

Commit hash that was tip of `bitcoin_hashes` at time of import:

 commit 54c16249e06cc6b7870c7fc07d90f489d82647c7

Includes making `embedded` and `fuzzing` per-crate i.e., move them into
`bitcoin` as hashes includes these also.

NOTE: Does _not_ enable fuzzing for `hashes` in CI.

Notes on CI:

Attempts to merge in the github actions from the hashes crate however reduces
coverage by not running hashes tests for beta toolchain. Some additional
work could be done to improve the CI to increase efficiency without
reducing coverage. Leaving for another day.
