Use new *Dirty traits from the digest crate
#153
Conversation
Updates all of the hash implementations in this repo to use the new `*Dirty` traits which support blanket impls of the original traits, which either consume the hasher instance or can be reset. This will also provide a marginal efficiency boost, at least until placement return lands (which, as it were, may be soon).

I think it could be worth to be consistent and use digest::Output<Self> across all crates.

The reason I couldn't here is because it doesn't impl Default, and digest::Output (presently, at least) uses the Digest trait:
https://github.com/RustCrypto/traits/blob/master/digest/src/digest.rs#L96
It could potentially use FixedOuput instead.

Hrmm, changing it to use FixedOutput is not trivial... it means you can't use it with Digest because not all Digests necessarily impl FixedOutput, and that kind of defeats the point.
I think we should leave it as-is. That said, I think we can fix the version used in the macro.

Dirty traits fit even better than I expected. |

Indeed, surprisingly easy refactor for what it is. I'll go ahead and merge and circle back on changing |
