when compiling I get this error ``` Marlin\src\feature\mmu\mmu2.cpp: In static member function 'static bool MMU2::load_filament_to_nozzle(uint8_t)': Marlin\src\feature\mmu\mmu2.cpp:924:5: error: 'filament_ramming' was not declared in this scope 924 | filament_ramming(); // Unloading instructions...

It works thanks, this pr adds important function for mmu operation

i wanted to test the latest changes today but printer keeps restarting with and without this pr

Expected behavior: Unloading Filament ramming sequence extruder keep unloading until no filament is detected. mmu unloading. Actual behavior: Unloading Filament ramming sequence filament still in extruder and damaged by mmu...

I just tested again no change. still same behavior: Unloading Filament ramming sequence filament still in extruder and mmu start unloading.
