Jack Grigg a06b406eb4 zcash_note_encryption: Doc fixes

Jack Grigg 1385c8cc41 zcash_note_encryption: Fix array size in Domain::extract_{esk, pk_d} 
Decrypted output size is `OUT_PLAINTEXT_BYTES`, which the decryptor
can always provide (either by decrypting into the correct size array
as now, or truncating the buffer before passing it to the domain).

Jack Grigg befb178c61 zcash_note_encryption: Pass cmstar_bytes to Domain::derive_ock

Jack Grigg d94482d5ac zcash_note_encryption: s/TryFrom/From on ExtractedCommitmentBytes bound 
This was left over from an earlier refactor where we could call a domain
API to extract cmstar from a note commitment (which could fail for
Orchard). This part of extraction was subsequently refactored into the
domain logic (and is rejected earlier for Orchard). The resulting bound
is wrong because it's always possible to serialize a scalar.

Jack Grigg 22d0991a46 zcash_note_encryption: Enforce ZIP 212 check on esk from outPlaintext 
It needs to equal the esk derived from the note (for v2 note plaintexts).

Kris Nuttycombe 3843f4ba2b Use ShieldedOutput trait for note encryption/decryption. 
This change modifies note encryption and decryption functions
to treat a shielded output as a single value instead of handling
the parts of an output as independent arguments.
