While Serai only needs the simple DLEq which was already present under monero, this migrates the implementation of the cross-group DLEq I maintain into Serai. This was to have full access to the ecosystem of libraries built under Serai while also ensuring support for it. The cross_group curve, which is extremely experimental, is feature flagged off. So is the built in serialization functionality, as this should be possible to make nostd once const generics are full featured, yet the implemented serialization adds the additional barrier of std::io.
