This is following up on #410 with the rest of the decoupled implementations, and addressing most of the review comments (I think?).

There are still some todos left for documentation, which I haven't filled in yet.

I've verified that tests & clippy pass with all combinations of features, but a lot of this I only know enough about to be dangerous, so I'd appreciate close looks at the actual implementations to make sure e.g. I've picked the correct library functions in each case.

Looks great overall. I think some macros would help reduce the duplication

should we have a default crypto backend or let users pick the one they want?

I mean, that's up to you. I personally think it's nice to have a reasonable default.

aws_lc_rs would be a good default

This comment is actually @sidrubs', I'm not entirely sure what they mean by that, whether it's not covered by tests, or docs, or...?

I'll have a go at reducing the duplication through some macros and addressing the other comments.

Alright, done some refactoring to reduce the duplication and re-enabled the WASM HMAC test cases. I checked that tests pass with both AWS-LC and Rust-crypto.
