Allow G10 L1 to set only front/back angles
Allow G10 L1 to set only front/back angles

Fixes issue where G10 L1 tool offset couldn't set I or J (front
angle/back angle) without including a geometry offset. Previously,
G10 L1 P1 I40.0 would generate an error ""G10 L1 without offsets
has no effect"). Now I and J are allowed as the only values on a
G10 L1 line.
