feat: add support for Non-interactive PoRep

[vmx]

This commit introduces new registered proof types in order to support ni-porep.

Also Rust >= 1.70 is needed due to the dependency on home v0.5.9.

[cryptonemo]

Can you rebase this on top of #97 instead of master, since that's pending the proofs release already?

[vmx]

OK, I've rebased. @cryptonemo Please do not squash this PR and yours into a single commit. Either merge them separately or at least a proper merge commit. It's very valuable to have the changes for Ni-PoRep in a separate commit. It helps when someone does similar changes (just like I used the Synth-PoRep commit as a template for my change).

It's very valuable to have the changes for Ni-PoRep in a separate commit.

You already know I don't agree here.

Also, I plan to push some changes because there are things I'd like to clean-up. So would you prefer I open a new PR or can we work collaboratively on this one?

[cryptonemo]

Actually, here's a better way -- let's just merge the original PR, merge this one, then I'll build on master. You have your valuable history and things get done either way? 🤷‍♂️

[vmx]

I think just merging the PRs in order is certainly less work and I'd prefer that :)

[cryptonemo]

Ok, good to rebase now. For FFI, we'll have to cut the releases first and then merge in order as well

[vmx]

It was automatically rebased. Feel free to merge.
