Module crypto 

Signature schemes for the slow path, one module each, all behind the same ports (crate::ports::CryptoIn / crate::ports::CryptoOut).

Scheme	Module	Feature	Owner
Ed25519	ed25519	ed25519 (default)	this crate
DSig	dsig	dsig	DSig
Outside the replica (card tops)	external	always	this crate
Model (tests only, not secure)	[model]	sim	this crate

A build picks one with RHDL_UBFT_SCHEME ([crate::Scheme]); both may be compiled in.

Modules
