Update tiny-keccak from 1.5.0 to 2.0.2

[iancoleman]

In sn_api the majority of dependencies use tiny-keccak 2.0.2 so it makes sense to have them all at the same version.

Sorry I had an old version of clippy which missed some stuff. Just updated and fixed and should now be passing.

Thanks for the tips on commit message style @bochaco, I'll follow that from now on :slightly_smiling_face:
