Implement heatbed cooldown routine

Browse Source 
- M888: Cooldown routine for the Anycubic Ultrabase (EXPERIMENTAL):
This is meant to be placed at the end Gcode of your slicer. It hovers over the print bed and does circular movements while running the fan. Works best with custom fan ducts.
- T<int>: Target bed temperature (min 15°C), 30°C if not specified
- S<int>: Fan speed between 0 and 255, full speed if not specified

Thanks to @kulfuerst for the suggestion!
