Add wheel to CI dependencies installation

[cthoyt]

This PR does the following:

• [x] Add pip install wheel to CI dependencies installation. This should make it go much faster, since apparently it's not available on the current config by default
• [x] Remove special installation of pyparsing (this should no longer be necessary since rdflib isn't a requirement anymore as of the changes in https://github.com/indralab/protmapper/pull/41 that were released in protmapper v0.0.24 yesterday)
• [ ] Remove special installation of cython (this should be handled by pyjnius since https://github.com/kivy/pyjnius/pull/594 made it to the 1.4.0 release at the end of August 2021)

@bgyori can we remove that pyparsing fix in the CI configuration too while we're changing things here?

Let's not do this one right now:

 Remove special installation of cython (this should be handled by pyjnius since Add pyproject.toml to specify Cython as a build requirement kivy/pyjnius#594 made it to the 1.4.0 release at the end of August 2021)

pyjnius is actually pinned to version 1.1.4 and it would take more work to change that.
