Fail to install on PyPy 7.3.9 (Python 3.9.12)

[Mujahid Anuar]

I got the following error when trying to install rapidfuzz on PyPy 7.3 (Python 3.9.12) on a RHEL 8.6 (redhat-release-8.6-0.1.el8.x86_64) machine:

      ********************************************************************************
      scikit-build could not get a working generator for your system. Aborting build.
      
      Building Linux wheels for Python 3.9 requires a compiler (e.g gcc).
      But scikit-build does *NOT* know how to install it on rhel
      
      To build compliant wheels, consider using the manylinux system described in PEP-513.
      Get it with "dockcross/manylinux-x64" docker image:
      
        https://github.com/dockcross/dockcross#readme
      
      For more details, please refer to scikit-build documentation:

  ERROR: Failed building wheel for jarowinkler
Failed to build jarowinkler
ERROR: Could not build wheels for jarowinkler, which is required to install pyproject.toml-based projects

I was wondering if this is an issue with PyPy or rapidfuzz itself?

[Max Bachmann]

I did not provide wheels for the jarowinkler package on pypy3.9 yet and you appear to have no c++ compiler available to build from source. I released a new version of the package, which provides these wheels. So you the installation should now work.

Wow, I didn't expect a response and a fix that fast. Thank you @maxbachmann! I tested v2.0.13 and it works perfectly on the above machine.
