Fusion 360 post processing - Coolant

Did a quick fix before I release v1.beta2 tonight to include the fix for the Grbl M3/M4 Laser On speed scaling issue.

This release doesn’t include the coolant changes we discussed or other refactoring work I want to do to the laser code but it does get that bug solved.

Please let me know how it works. I ran 1 test and it looked good so please review and ensure it is what you expected.

The new release is here Flyfisher604 Fusion 360 Post Processor (v1.beta2) available .
