Suppressed z-hop min floor when park moves aren't defined for the mmu sequence to keep nozzle on purge block during toolchange. e.g. when the user has used variable_park_toolchange : -1,-1, 0, 0, 2

Also incorporated Prusa style stamping moves as part of tip form macro in cooling move loop (only stamps on even moves). Controlled using 3 variables: use_stamping (true | false), stamping_insertion_distance mm & stamping_insertion_speed. Currently using unloading_speed_start value for the retraction rather than creating another parameter. Need to check and review move offsets as stamping_insertion_distance "should" technically be from the middle of the cooling tube according to Prusa slicer

Still testing so not ready to merge.

Fixes #486

Happy to add this when you are complete. Can you ensure the defaults in FORM_TIP macro default to turning stamping off in the absence of the variables defined in mmu_macro_vars.cfg. That way I don't need a version number change to force users to do the "upgrade install". I.e. everything will work with a simple update-manager refresh. Users who want the functionality can of course run ./install.sh to upgrade. The reason is that I've had a lot of forced updates lately and I have v3.0 coming very soon..
