Support signing Monero TXs with multiple inputs
...
Remove's CLSAG's msg Rc for the msg available through AlgorithmMachine.
Potentially slightly more inefficient, as it needs to be converted from
a slice to a [u8; 32], yet removes a re-impl.
Also removes a match for an if.

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.

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