GCodeAnalyzer now recognizes tool-changing commands with MakerWare and Sailfish flavor

These firmwares use M135 Tn and M108 Tn commands for changing active tool, which the analyzer did not recognize. The toolpaths were then rendered in wrong color, extruder offset etc. This surfaced in issue https://github.com/prusa3d/PrusaSlicer/issues/2566
