Kitsune2 is making use of the bytes crate--it would be more efficient if tx5 did the same.

The sbd-e2e-crypto-client crate returns received data as a bytes::Bytes. The tx5 Endpoint and supporting dependency traits convert this into Vec<u8>s which kitsune then translates back into bytes.

Staying with bytes would eliminate a large number of mem copies.
