High speed anti jam filament drive for Makergear M2

Main goal: stop filament drive from jamming and increasing extrusion speeds for highly flexible materials.

A couple weeks ago I met the founder of MaukCC, Jos Scheepers. He taught me that when the filament loses touch of the driving gear in the filament drive it should not have any space for bending, see the attached image also. I implemented this and am about to test it.

This thing is a remix of https://github.com/MakerGear/M2/blob/master/Printed%20Parts/STL/M2%20Filament%20Drive%20r2.s
