[FeatureRequest]: Filament sensor/monitor used for load/unload

[T3P3]

Is your feature request related to a problem? Please describe.

It would be useful if the filament monitor or a filament sensor could be configured to act as a filament "endstop"/trigger (present/not present) to allow for it to be used in filament load and unload macros.

Describe the solution you propose.

Multiple potential ways to do this: Provide a filament present/not present state in the OM Provide a trigger based on filament movement/no movement or present/not present

Describe alternatives you've considered

For a switch based presence sensor it can be reconfigured as a trigger during the load/unload macro and then configured back to a filament sensor at the end of the macro.

Provide any additional context or information.

I do this currently in macros. What is the enhancement being requested?

Stall detection can also be used to load filament until it reaches the hot end.

Using a filament detection switch to control unloading filament would be appropriate if the filament sensor was located some distance before the extruder drive. I don't see how a filament sensor could be used to control loading filament.

Look at the orbiter projects filament sensor
