sudo install python dependencies on OSX (valhalla#4209)

* sudo install python dependencies on OSX

* well then.. install cython urgh

* huh, wrong python3 maybe, pre-commit depends on pyyaml 6.0 and installs without issues, 5.9 should have a wheel as well, but when downgrading pip decides to build from source instead.. urgh. last resort: pin pre-commit to a version which depends on pyyaml < 6.0, but eventually we'll need to do the conan switch to 2.0

* get rid of cython again..
