Remove `signature` and `util/signature` packages. Re-implement their functionality in new `crypto` package. Generalize the approach of digital signature computation and verification by adding `Signer` and `PublicKey` primitives similar to standard `crypto` package. Support already exising in protocol signature schemes. Signed-off-by: Leonard Lyubich <leonard@nspcc.ru>
