New package: rapidcheck
https://github.com/void-linux/void-packages/pull/45614

Description:
Rapidcheck is a QuickCheck clone for C++.
This package is used by newer versions of the Nix package manager and so it needs to be introduced for the 'nix' package to be updated.

Rapidcheck has no versioning or tags, the revision supported and used by Nix is currently being used when building this package.
