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.
f690b8e362 Be more liberal when parsing Denomination (Tobin Harding)
628168e493 Add missing white space character (Tobin Harding)
Pull request description:
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

- ~ Fixes a bug in #691 about taking secp context as a reference instead of consuming it. This should have not passed my review, but this is easy to miss. ~
- Makes the display on taproot hashes forward instead of the reverse (because the BIP prints in a forward way, I think we should too and it is more natural. )

There is no reason to force users to use one particular form when
providing a denomination string. We can be liberal in what we accept
with no loss of clarity.
Allow `Denomination` strings to use a variety of forms, in particular
lower case and uppercase.
Note, we explicitly disallow various forms of `Msat` because it is
ambiguous whether this means milli or mega sats.

b454cf8e15 Return None from merkle_root functions (Tobin Harding)
7a8b017ea3 Use correct spelling of merkle (Tobin Harding)
Pull request description:
~Do two minor refactorings to the `bitcoin_merkle_root[_inline] functions.~
This PR has grown, is no longer a refactoring because the two functions have been changed to return an `Option`.
First patch is cleanup. Here is the commit message for the second patch
```
The merkle_root of an empty tree is undefined, this is the only error
case we have for the two `bitcoin_merkle_root*` functions. We can fully
describe this error case by returning an `Option` if args are found to
be empty.
While we are at it, refactor out a recursive helper function to make
reading the code between the two functions easier.

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.
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.
The merkle_root of an empty tree is undefined, this is the only error
case we have for the two `bitcoin_merkle_root*` functions. We can fully
describe this error case by returning an `Option` if args are found to
be empty. We can do the same for the wrapper functions in `block`
module.
While we are at it, refactor out a recursive helper function to make
reading the code between the two functions easier.
