Subject: [PATCH] AvailabilityChecker: Remove hard requirement on
 tobii_research

Now tobii_research [1][2] module does not need to be installed
to be able to use mouse emulation.

[1]: https://developer.tobiipro.com/python.html
[2]: https://pypi.org/project/tobii-research/

This change removes 'import tobii_research as tr' from
checkPythonEnvironment() method, and adjusts checkEyeTracker() and
getEyeTrackerName() to work correctly even if tobii_research is not
installed.

Not tested yet.

The problem with requiring tobii_research is that it requires specific
Python version to be able to be installed: 3.8 or 3.10 [3][4][5]
