This PR adds a new approach to fuzz testing where we randomly create RegExp ASTs and then convert them to RegExp strings.
This testing approach has found many issues that the existing fuzz tests did not catch. Some of the generators are currently disabled due to known issues and GitHub references are provided in the code.
