Support modality of G0 and G1

[ronindev]

Hello!

G00 and G01 are modal commands, so they can me omitted in gcode file if mode does not changed. CAM that I currently using to make PCBs GGEasy use that approach. For example:

;              Tool: Engraver (30° 0.2 mm tip)
;     Tool Stepover: 0.1
;    Feed Rate mm/s: 1.33333
;   Tool Pass Depth: 0.1
;             Depth: 0.03
;              Side: Bottom
G21 G17 G90
M3 S1000
G0Z6
X65.541Y23.855
Z1
G1Z-0.03F80
X65.523
X65.332Y23.872
X65.313Y23.875
X65.128Y23.925

g-code-utils does not support such GCode for now.

I've tried to solve that issue, in my fork. It's ugly code, because scala and FP too complex for me. Just have a look, it's like a proof-of-concept of modifying coordinates instead of generating new GCode commands.

Hi there! I'm sorry that it took me so long to tackle this one, I've been very busy in the past few months. I've just released a new version (1.2.1) with a lot of improvements in G-Code parsing which include supporting omitted and incremental/partial commands. That kind of g-code shouldn't be a problem anymore 😄 Thanks!
