We have full tool offsets now.
Allow use of several simultaneous tool offsets with G43.2 H

To use tool 1 with the sum of offsets 1 and 10, program:
T1 M6
G43 (or G43 H1: replace any existing offset with T1's)
G43.2 H10 (also add in the T10 offset)

You can sum an arbitrary number of offsets by calling G43.2 more times.
There are no built-in assumptions about which numbers represent geometry
and which are wear, or that you should have only one of each.
