Add TLS Certificate Compression (RFC8879) - v2

[sharksforarms]

I took a different approach after investigating the bogo tests and boringssl. Previous PR: #445

No longer include compression dependencies and leave this open to the client libraries to use/configure as they wish.

This PR implements RFC8879

Issue: #436

Rebased with master to keep this branch up to date

@sharksforarms Is this branch something you would be interested in rebasing on main and putting up for review?

Hi @cpu, thanks for taking a look. I'm interested yes. Please advise if the design (callback approach) is still appropriate or if this should change, I'll attempt to rebase but I believe it may be too far gone 😅

Great!

I haven't had a chance to familiarize myself with RFC 8879, or to read your branch with too much care but I think it's the right place to start. It's possible that @ctz has more existing context/thoughts on the matter.

I started to re-work on this a while back here: main...sharksforarms:rustls:sharksforarms/cert-compression

If anyone wanted to pick this up, feel free, at the moment I don't have enough time to dedicate to this.

I'm going to close this. I will shortly be bringing forward a PR for this, that reuses some parts of this one. Thanks!
