This commit adds proving and verification functions for discrete logarithm equality. From the spec (https://github.com/discreetlogcontracts/dlcspecs/pull/114): "As part of the ECDSA adaptor signature a proof of discrete logarithm equality must be provided. This is a proof that the discrete logarithm of some X to the standard base G is the same as the discrete logarithm of some Z to the base Y. This proof can be constructed by using equality composition on two Sigma protocols proving knowledge of the discrete logarithm between both pairs of points. In other words the prover proves knowledge of a such that X = a * G and b such that Z = b * Y and that a = b. We make the resulting Sigma protocol non-interactive by applying the Fiat-Shamir transformation with SHA256 as the challenge hash."
