Text outline directly in slicer

Added text in slicer lacks contrast, if printed with certain colors. (See 1. on attached picture) In order to enhance contrast, one can modify the text in CAD, to have an outline. This is achieved with extruding the outline as additonal body, to be "Painted" later in slicer. This process is very cumbersome, especially with some fonds and long texts. The possibility to have a "outline" on text option, directly in PrusaSlicers text editor, is going to make this process much more convinient. One also might set the thickness in perimeter sized increments. (See 2. and 3. on attached picture)
