 - Introduce a new method `ProveCommitSectorsNI` (method 36), which performs a non-interactive proof for CC sectors, without a preceding PreCommitSector message (ie, this method rejects sectors that were already pre-committed. Such sectors must be activated with one of the existing ProveCommit methods). The method can be used with seal proofs or aggregate proof (but only one option can be chosen per call); the return type is the same  as `ProveCommitAggregate`.
