Update on SupraNational PC2/C2 <> Lotus-Miner

One of our goals this quarter was to allow storage providers to leverage the SupraNational PC2 and C2 proofs to reduce the sealing times for these tasks significantly!

This week the PR enabling delegating PreCommit2 to call external libraries in lotus-workers & lotus-bench, and thus enabling one to use SN PC2, is now under code-review. Similarly the proofs-team has a PR enabling the SN C2 proofs behind a feature flag in review.

We are awaiting some final dependency releases before we can 🚒 and start leveraging these features. We will updated you all once these PRs land!
