The PodSigner trait was taking `&mut self` in the `sign` method, but the signer doesn't need mutation in the Shcnorr implementation. Remove the `mut`. Previously the PodProver trait was also taking `&mut self` in the `prove` method, and we had many tests creating a `mut Prover/mut MockProver`. Remove all those `mut`. Breaking change: `PodSigner` trait method `sign` replaces `&mut self` by `&self`
