Threading

GRBL doesn't support threading at the moment. There are some implementations (CNCL and grblgru) that support threading by using a stepper for driving the spindle. This works very well but it takes some effort to implement.
I have added spindle sync threading (G33) to the GRBL-L (Arduino Uno) and GRBL-L-Mega (Arduino Mega) version. G33 threading is supported by CNCL.
