Loose laser movement sync on engraving

[Ams-Laser]

When doing highspeed (300mm/s) raster engraving syncronisation between laser pulses and movements is lost, resulting in ghosting and deformed output,

had similar issue with FluidNc, fixed by using I2S_STATIC instead of I2S_STREAM

dont know how grbl hal manages i2c pulsing engine but a fix would be to use static mode when laser mode is set to 1

hope ou can help.

Thanks

I have now changed the code to use static I2S mode but do not have hardware to test on. Please test and report back.
