We have two types for tweaked/untweaked schnorr public keys to help users of the taproot API not mix these two keys up. Currently the `taproot` module uses 'raw' `schnoor::PublicKey`s.
Use the `schnoor` module's tweak/untweaked public key types for the `taproot` API.
Fixes: #725
Please note, I saw this was labeled 'good-first-issue' but I ignored that and greedily implemented a solution because of two reasons
1. We want to get taproot stuff done post haste.
2. I'm struggling to follow what is going on with all the taproot work so this seemed like a way to get my hands dirty.

Currently we calculate the parity during `tap_tweak` but do not return
it, this means others must re-do work done inside `tap_tweak` in order
to calculate the parity. We can just return the parity along with the
tweaked key.
Keeping inline with the method on `UntweakedPublicKey` that outputs a
`TweakedPublicKey` we can use the same name, for the same reasons.
Use `dangerous_assume_tweaked` as the constructor name to highlight the
fact that this constructor should probably not be being used.
We currently run `tweak_add_check` and use the result as a conditional
branch, the error path of which uses `unreachable`. This usage of
`unreachable` is non-typical. An 'unreachable' statement is by
definition supposed to be unreachable, it is not clear why we would need
to have a conditional branch to check an unreachable statement.
Use `debug_assert!` so programmer errors get caught in un-optimised
builds but in optimised builds the call to `tweak_add_check` is not even
done.

Calls to `unwrap` outside of tests are typically unfavourable.
In memory writers (`Vec`) do not error. We can use `expect` with a
descriptive message string to indicate this.

Sink writers do not error. We can use `expect` with a descriptive

Calls to `unwrap` outside of tests are typically unfavourable.
Hash engines do not error when calling `consensus_encode`. Instead of
the current usage of `unwrap` we can use `expect` with a descriptive
string as is done in other parts of the codebase.
In the name of uniformity use the same error message as argument to
`expect` througout the codebase.
Use "engines don't error" instead of "engines don't err".
f2a6827982 Fix BinaryHeap direction for Taproot Huffman Encoder (Jeremy Rubin)
cccd75d004 Fix Weighting Addition to never error on overflow + prevent overflows from ever happening with wider integers (Jeremy Rubin)
Pull request description:
I noticed one cleanup & one bugfix while looking into the huffman algorithm:
1) the cleanup: we can use a u128 to guarantee no overflows, and saturating_add to guarantee reasonable behavior in any case
2) the bug: the binary heap is a max heap so the behavior ends up merging the nodes of the most likely entries repeatedly. a huffman encoder requires merging the least likely elements, so it should be reversed.

eb8278fd2e util/address: Improve docs (Tobin Harding)
Pull request description:
Improve documentation of the `address` module by doing:
- Add full stops to all sentences
- Use code ticks even inside links e.g., [`WitnessVersion`]
- Use 100 character line length
- Do grammar fixes
- Use comment sections (e.g. `# Returns`)
- Use 3rd person for function comments e.g. 'Converts foo to bar' instead of 'Convert foo to bar'
- Use ticks for scriptPubkey
This patch does a single file because a bunch of these changes pick an
arbitrary stlye, if we can bikeshed on this PR then future PRs should be
able to progress more quickly. I'll take lack of comment on any of the
above as approval and I'll attempt to be uniform when doing the rest of
the codebase. I plan on just chipping away at this, I can only do so
much docs work in a day without getting bored of it :)
Notes:
- I didn't touch 'segwit' vs 'SegWit', seems both are widely used.
- Using ticks inside links may be an overkill but seems more correct?
- I'm not totally sure where the line is in the Rust ecosystem between
readability in an editor and rendering as HTML, open to input on this.

e04795093f Add unit test for bitcoin_merkle_root functions (Tobin Harding)
Pull request description:
We test `bitcoin_merkle_root` over in the `blockdata::block` module.
Although the `bitcoin_merkle_root` and `bitcoin_merkle_root_inline`
functions are almost identical there is enough index manipulation done
that it is not immediately obvious that the code is error free.
Add a unit test that verifies that the two functions return the same
resulting merkle root.

Improve the rustdocs for the various `Address` constructors by putting
the brief description on a separate line with further description in its
own paragraph. This is the layout best practice for function documentation
using rustdocs.
Also, favour 'creates' over 'constructs' because it is more common in
the docs of this struct.
