[ENHANCEMENT] Experimental menu - add a reverse option for the filament sensor (Bondtech IFS extruder)

[Eldenroot]

Enter what type of printer or upgrade the enhancement applies to. Printer type - [MINI+] Optional upgrades - [Filament Runout Sensor + Bondtech IFS extruder]

Is your suggested improvement related to an existing problem? Please describe. When you use the new version of Bondtech IFS Extruder for Prusa Mini/Mini + (the older version of Bondtech extruder is discontinued), you have to switch the wires in the connector (filament sensor) - switch red and black wire.

Describe the expected functionality I believe this can be solved in firmware. This makes sense to me to add this new setting to the experimental menu.
