Added support for G66.1 macro call. Changed behaviour of G50 and G51 (and the G48 and G49 shortcuts) controlling feed rate and spindle RPM overrides. Added support for G10L0, reload file based tool table. Fixed buggy handling of G43 - apply tool offset from tool table. Refactored the encoder HAL/API to make it more flexible and as a first step to support rigid tapping. See the changelog for further details.
