In BIP0032, m is used as a variable for the root extended key. It is not
meant to be used as a constant prefix when serializing paths.
Update the DerivationPath parser to no longer require the m prefix.
Remove the m prefix from the unit tests and the bip32, ecdsa-psbt,
and taproot-psbt examples.

Implementing this for spendinfo is really complicated because it
contains some cached data without retaining the components that are used
to compute them.
Users should serde the 1) NodeInfo and 2) internal key and reconstruct
TaprootSpendInfo from it.
Cleanly separate `TapTree` and `NodeInfo`. Fix serde not respecting
invariants for several data structures
Repurpose some tests from removed taproot builder for taptree
"schnorr" is a dirty word; the current `schnorr` module defines a
`Signature` that includes a sighash type, this sighash type is a bitcoin
specific construct related to taproot. Therefore the `Signature` is
better named `taproot::Signature`. Note also that the usage of `schnorr`
in `secp256k1` is probably justified because the
`secp256::schnorr::Signature` is just doing the crypto.
While we are at it, update docs and error messages to use "taproot"
instead of "schnorr". Also change function names and identifiers that
use "schnorr".
962abcc963 Add serde regression tests (Tobin Harding)
Pull request description:
Attempts to add regression tests for _all_ types defined in `rust-bitcoin` that implement `Serialize`/`Deserialize`.
- Add a `tests` directory and implement regression tests in there
- Use files for input hex and output bincode to reduce source file clutter
- Copy test block and `include_bytes!` usage from RCasatta's [PR](https://github.com/rust-bitcoin/rust-bitcoin/pull/750)
- Uses Kixunil's macro suggested below
- Adds a single regression test to `util/taproot.rs` for private types
## Note to reviewers
- Uses JSON for opcodes in a separate file (`tests/regression_opcodes.rs`), for all other tests uses bincode.
- Bypasses the order issue for maps by only serializing maps with a single element - is this correct?

This transaction broke past versions of `rust-bitcoin` and LND so this
adds a test to avoid reintroducing the problem in the future.

In order that we can safely change/maintain de/serialization code we
need to have regression tests with hard coded serializations for each
type that implements serde.
It is enough to test a single serde data format, use JSON for `opcodes`
and bincode for other types.
Do regression testing in a newly added `tests` module.
