Provide Known Answer Tests

[mberry]

Hashes and ciphers usually have known answer tests associated with the reference implementation.

This provides a canonical digest for anyone writing their own implementation of LXR Hash to check against.

at the moment, we have:

LXRHash/lxrhash_test.go

Is that good enough or are we talking about a list of hundreds/thousands of them?

[mberry]

Yeah that's great, a few is fine. Some hashes/ciphers seem to go overboard testing 1000's of edgecases, doubt that's of any use here.

Wrote a LXR implementation and trying to keep it simple wrt keeping up with any algorithm changes. Hopefully a KAT file or some notes in the readme can help anyone else doing the same.
