Sync variant of MultihashHasher that refines return type of the digest
to MultihashDigest. It is subtype of MultihashHasher so implementations
of this interface can be passed anywhere MultihashHasher is expected,
allowing consumer to either await or check the return type to decide
whether to await or proceed with return value.
SyncMultihashHasher is useful in certain APIs where async hashing would be
impractical e.g. implementation of Hash Array Mapped Trie (HAMT).
Takes binary input and returns it (multi) hash digest. Return value is
either promise of a digest or a digest. This way general use can await
while performance critical code may asses return value to decide whether
await is needed.
