Probably, do #10 first.

See Crypto.Mac.Lazy, Crypto.Mac.Stream, and crypto-sodium-streamly.

I think we should restrict the scope of this issue to multi-part messages as implemented in Libsodium, i.e. we lazily consume a message and produce a signature.

Streaming signed data should be a separate concept, which is not implemented in Libsodium, and we should do something like the Saltpack’s format and/or Sodium’s encrypted stream format.

Probably won’t happen (see https://github.com/serokell/haskell-crypto/issues/17#issuecomment-709686119).
