Pull request description:
Rust nightly as of 2024-05-27 has a new lint which detects list items which are continued by a non-indented line. Markdown treats these as single list items, which they sometimes are, but sometimes we intended them to be on a separate line.
Also changes the docs for `UntweakedKeypair::tap_tweak` because the existing ones were overly technical and out-of-date.
Also fixes a minor "no need to create a vec then dereference it" lint in the examples.

1b40550ce8 Add an AddressData type (Tobin C. Harding)
Pull request description:
In the 0.32.0 release we removed the `address::Payload` struct because it was deemed an implementation detail. As a byproduct of doing so we made it impossible for users to match on an enum and get the address payload (or data).
- Add a public `AddressData` enum that holds an address' encoded data.
- Add a conversion function to `Address` that returns the data enum.
This patch is additive and is expected to be backported and release as a `0.32` point release.

We would like to move the dependency on `hex_lit` to be a
dev-dependency but currently are using it in bench code. The bench
code is enabled if any downstream crate tries to build with
`--cfg=bench` and during such a build our dev-dependencies are not
available.
We also have the `test_hex_unwrap` macro in the `hex` crate and since
the bench code is more or less test code (and the macro call is not
being benchmarked) we can use that macro instead.

Currently we use the `Hash` trait in a bunch of places to call
`all_zeros`. We are attempting to improve the `hashes` API and this
usage is both unnecessary and also hindering that effort.
Use the concrete type (e.g. `BlockHash`) instead of calling through the
trait method.

47dc4a3180 feat(pow): add difficulty adjustment calculation (Rob N)
Pull request description:
Hi, I hit a roadblock with the current `pow` API. As far as I can tell, the only workaround to calculate the next work required similar to `bitcoin/src/pow.cpp` is to use a general big integer library, convert the `Target` to bytes, do the math, and convert back to `Target` from bytes. I have also been working with [Floresta](780ea8d0b0) and their [solution](780ea8d0b0/crates/floresta-chain/src/pruned_utreexo/consensus.rs (L187)) was to fork off and exposed the `U256` struct publicly on their branch. I think these home brewed difficulty adjustment solutions will continually pop up, so I created a `from_next_work_required` method to return a `Target`. My work veers significantly from #2180, as I only provided a single method to do so, without further guidance on when exactly this retarget occurs.
I am happy to add tests once I get further direction from maintainers if this as a likelihood of being accepted or not. Thanks.

Currently we have two macros used when creating array wrapper types,

Improve the macros by:

that return arrays
- Add `as_bytes` to return a slice
- Add `to_bytes` to return a vector

First three patches are preparation, improvements to the units tests in `sha256t`.
From the final patch:
Displaying backward is an anomaly of Bitcoin Core's early days and the
double SHA256 hash type. We should not let this unfortunate beast leak
out into other places.
Default to displaying forward when creating a new tagged hash and remove
all the explicit attributes from `bitcoin` that just clutter the code.
This is an API break and may quietly break some users downstream - eventually we should stop doing that sort of thing.

Currently we require indexing trait bounds as well as `Borrow` on the
`Hash` trait. We also already implement `AsRef`.
It was observed that `Borrow<[u8]>` does not best describe what we want
from the `Hash` trait implementor but rather `AsRef<[u8]>` does.
Remove all the inexing trait bounds. Remove the `borrow::Borrow<[u8]>`
trait bound. Add a `convert::AsRef<[u8]>` trait bound.
This leaves the `Borrow<[u8]>` implementation for hashes created with
`hash_newtype`, I'm not sure if this should be removed or not.
During the recent release cycle we left `bitcoin` on the last rc
version.
