NUT for Discreet Log Contract support

[conduition]

Today I published a first-draft of an idea for discreet log contract integration for Chaumian Ecash mints.

Before I go to the trouble of writing up a NUT submission, is this even the right place for such an idea? Or would DLCs be outside the scope of Cashu?

Naturally I don't think DLC support should be mandatory for any cashu implementation. But DLCs could be a highly desirable feature for ECash... something which might incentivize non ecash users to take the plunge. DLCs could offer a sort of programmable functionality on top of Ecash, outside of simple unconditional payments, without adding much complexity to the mint itself.

There are already NUTs for DLEQ Proofs, P2PK and HTLCs, so yeah I think it's nut-worthy and fine to have optional specs
