Update for sphgeom pip install

sphgeom no longer has a requirements.txt file, so this commit removes
the step from the build_and_test workflow that executes such a
requirements.txt file.

Secondly, the install_requires dependency listing in setup.cfg now
installs sphgeom from GitHub, making the sphgeom installation from a
requirements.txt file unnecessary.
