Updated to point at a much newer version of the library. Moving forward before was difficult because of a segfault introduced to rapidcheck when it's static library was optimized or stripped. That was fixed by a commit on 19 December 2020.

Motivation for this change

The rapidcheck library is sitting at a version that is more than two years old. There is functionality that has been added since that time that it would be nice to be able to access without having to override the package.
