Context
With untrusted input a caller could cause this library to panic if attempting to recover the signature from a payload which has an invalid R/S value.
This PR guards against this scenario by checking R/S values in signing/decoding.
Test plan
As a follow up I want to add additional fuzz tests as well. This should come in the next few days
