Ad-hoc derives for [DirectorySignatureHash] impls, avoiding copypasta bugs

Input

• pub enum DirectorySignatureHashAlgo
• Unit variants
• Each variant with #[deftly(hash_len = "N")] where N is the digest length in bytes.

Generated code

• pub enum DirectorySignaturesHashesAccu, with each variant a 1-tuple containing Option<[u8; N]>. (These are None if this hash has not been computed yet.)

• DirectorySignaturesHashesAccu::parse_keyword_and_hash

• DirectorySignaturesHashesAccu::hash_slice_for_verification

This is a derive_deftly template. Do not invoke it directly. To use it, write: #[derive(Deftly)] #[derive_deftly(DirectorySignatureHashesAccu)].
