SigmaProtocol/sigma-compiler: Crate for automatically generating code for sigma zero-knowledge proof protocols of more complex statements than are supported by the sigma-proofs crate. The statements given to this crate are compiled into statements about linear combinations of points, and transformed into the sigma-proofs API. @ 9a00db39b37b3e4d59971d4ff6c5de50bcd42f8a
