This resolves issue #2036
The original problem is that some laser firmwares allow LF line endings ("\n") but not CRLF ("\r\n"). The line endings work correctly in the paid software, LightBurn. In my case, I have the Creality Laser Engraver CR Falcon SE which shows the firmware as Grbl 1.3a.
This PR adds a checkbox in the advanced options to use LF line endings on the exported gcode file. The checkbox is unchecked by default since most users probably don't need this.
