One of the more "reliable" ways to check for fonts on the current system with the help of MatPlotLib (and FontTools).

Returns list of dictonaries, where each dictonary denotes a single font, with a Path object, the name, the font family
and the style.

Tested on Win10 & Ubu18.04 with Python 3.8.3 + Matplotlib 3.3.2 + FontTools 4.16.1
