Cutting motion for two dimensional cutting action

[ksummers92]

• Added additional movement axis to cutter action to support non-linear cutter such as this cutter to allow for smoother operation and provide more leverage
• Update mmu_macros_vars.cfg defaults to include a y-axis dimension to the compressed position
• Added some logic to _FILAMETRIX_DO_CUT_MOTION macro to allow backwards compatibility for existing configurations with single dimensional compressed location
  • It assumes that the omitted second dimension is the same as the park location coordinate
• Tested with and without y-axis dimension provided and operation works as before
• Tested switching to y-axis cutting direction as the primary direction and it also works
• Attached video shows exaggerated cutter motion in which x and y position are changing

variable_pin_loc_compressed would need to be upgraded in install.sh otherwise this would break previous installs. There is a function called:
read_previous_config() {
Logic should be added at the end of this function (similar to examples that are already there) that convert a previous scalar value to an list of 2 elements. Make sure this is tested to "upgrade" then run again to verify no further changes. I.e. the logic correctly spots a scalar value

Ah, I missed the fact that you handle scalar and a list in the code. Perhaps update the comment for variable_pin_loc_compressed to explain x or y or x,y capability...

I am not familiar with bash enough to update the install.sh to do what would be appropriate to update the parameter, so I decided to handle it this way. I tried to take a stab at it, but I am not sure how to detect if an variable(?) has a length of two? Or contains a ","? The syntax of what it is seeing when pulling out the parameters is lost on me...
