Initial add of Neptune 4 Plus profile (#2980)

* Initial add of N4Plus profile

Still some tuning to get it "right" but way better than nothing or just copying the Max profile.

* Fixing machine_start and manual filament change

Adding PRINT_START to the machine_start_gcode
Adding manual_filament_change override to True since this printer doesn't have automatic filament change.

* Adjusting accelerations and removing Z-Hop

Bumping accelerations to stock levels for all sizes and removing Z-Hop by default.

* Adding Z-Hop back in to be safe

Getting more stringing with Z-hop on but also rubbing prints during some moves.

* Removing print_start and lower accels a little

PRINT_START is automatically called on this printer so removing it from machine start gcode
Lowering accelerations a tiny bit. May bump it back up later but wanted a safer value.
