Filament change option

[Baddflash]

Is your feature request related to a problem? Please describe. This firmware removes the ability to swap filament during a print, the M600 command works when sent via Gcode menu so the option is enabled in marlin but not screen firmware.

Describe the solution you'd like Add the ability to swap filament during print, ie issue the M600 command via button on print status screen, I have created a modified print status screen and popups for the purpose already.

Describe alternatives you've considered I have tried to resolve the issue myself but do not have the necessary programming knowledge to understand the limited documentation available regarding the DWIN screens. While this can be preprogrammed into the Gcode file it has been far more convenient to swap at my discretion.
