A user pointed out on Slack that trying to make a deal with a 64GB SP with piece size of 55GB fails

lotus client deal bafykbzacedpyjxesatqb7s4ltsdcfldupqjpqepahxsthgkcdtsa7f3ldlcb4 t031080 0 518400
ERROR: failed to start deal: computing commP failed: commpWriter.Sum failed: generating unsealed CID: Piece is larger than sector.

Proposed Changes

I think it is safe to just assume the largest supported sector size here (64 GB) and leave it at that, but I'm not sure.
