- G54 work coordinate system support. Up to 6 work coordinate systems (G54-G59) available as a compile-time option. - G10 command added to set work coordinate offsets from machine position. - G92/G92.1 position offsets and cancellation support. Properly follows NIST standard rules with other systems. - G53 absolute override now works correctly with new coordinate systems. - Revamped g-code parser with robust error checking. Providing user feedback with bad commands. Follows NIST standards. - Planner module slightly changed to only expected position movements in terms of machine coordinates only. This was to simplify coordinate system handling, which is done solely by the g-code parser. - Upon grbl system abort, machine position and work positions are retained, while G92 offsets are reset per NIST standards. - Compiler compatibility update for _delay_us(). - Updated README.
