Daira Hopwood fa1bd3773a zc_utils: Enforce canonicity in parse_compact_size. 
(It's not strictly needed for generating test vectors, but just in case this code gets reused.)

Daira Hopwood ce388d3783 Further simplify parsing. 
This also ensures that the encoding ends with a receiver value, not a type or length.

Kris Nuttycombe 503a57bcbb Add test vectors for unified address encodings. 
This copies in the reference implementation of bech32m,
so that we can remove the 90 character length limitation.

Jack Grigg 3179b97362 Fix output for Orchard note encryption test vectors 
The test vectors were being generated correctly, but the output was
still Sapling-specific (rather than including Orchard components).

Jack Grigg fea2456bef Fix Orchard key components test vectors 
- Removed `note_r` (scalar copied from Sapling)
- Added `note_rseed` (bytes)
- `note_psi` needs to be derived from `note_rseed`
- missing `dk`, `note_rho` from output

Jack Grigg 445c2602f4 Rename header() to version_bytes() 
Now that the v5 transaction format has an actual header region, this
old naming makes less sense.

Jack Grigg bc75d044a1 Use specific tx formats compatible with sighash algorithms 
ZIP 244 is only defined for v5 transactions, so use the TransactionV5
type directly; likewise use LegacyTransaction with the ZIP 143 and
ZIP 243 APIs.
