Version 0.22.0

This version is quite large. Among the bugfixes there's also a big rewrite of the parser which is more generic and should support slicers that don't have clearly marked layer changes etc. like Cura. However, filaswitch does check the slicer header during startup and if no known slicer is found, it will not work.
Currently supported slicers:

• Prusa Slicer
• Simplify3D
• KISSlicer
• Cura (not fully tested)
  If there's a slicer or a version of a slicer that isn't recognized, create a issue so I can take a look at it
