* Added authors and licenses and plugin access to crypto related files * removed `rz_hash` and related files * introduced `rz_msg_digest_*` with plugins * updated all old methods with newer ones. * added HMAC support to `rz-hash` (moved key option under `-K`) * removed wrong algorithms on `woD`/`woE` * fixed parity digest size * fixed the behaviour on all hash functions * added unit test for hash * optimized code for HMAC key calculation * removed hash legacy tests
