replace deprecated failure crate with thiserror

this changes the public API in that all our methods now return a proper
ProtocolError crate. Needed change anyways to properly deal with all our
errors in the long run.

Will still need to do a pass through the crate to remove all existing
unwraps where it makes sense.
