Added Github action to build wheels.

Here is an example result of what is in a wheel:

Windows is giving these errors but the wheel seems to still be built:

The wheel builds, I then remove the conda installed ipopt and numpy and install the wheel with pip. Once installed I try to run and example and get this:

Successfully installed cyipopt-1.3.0.dev0 numpy-1.23.5
Traceback (most recent call last):
  File "/home/runner/work/cyipopt/cyipopt/examples/hs071.py", line 20, in <module>
    import cyipopt
  File "/usr/share/miniconda/envs/test-environment/lib/python3.10/site-packages/cyipopt/__init__.py", line 12, in <module>
    from ipopt_wrapper import *
ImportError: libipopt.so.3: cannot open shared object file: No such file or directory
Error: Process completed with exit code 1.

Looks like ipopt is not included in the wheel.

Tried auditwheel as suggested at https://github.com/mechmotum/cyipopt/issues/41#issuecomment-1435996883 but get this error:

auditwheel: error: cannot repair "wheelhouse/cyipopt-1.3.0.dev0-cp39-cp39-linux_x86_64.whl" to "manylinux_2_5_x86_64" ABI because of the presence of too-recent versioned symbols. You'll need to compile the wheel on an older toolchain.

Should try this: https://github.com/messense/auditwheel-symbols

This explains that building wheels from conda binaries may be possible but not trivial. https://github.com/pypa/cibuildwheel/discussions/773?sort=top
