Expands its test to test all possible ring indexes, though just 0 and a
single n would be sufficient.

Correct discrepancies with the IETF draft
...
While all the transcript/extension code works as expected, which means,
they don't cause any conflicts, n was still capped at u64::MAX at
creation when it needs to be u16. Furthermore, participant index and
scalars/points were little endian instead of big endian/curve dependent.

Implement a CLSAG algorithm extension which also does key images
...
Practically, this should be mergeable. There's little reason to do a
CLSAG and not also a key image. Keeps them isolated for now.
