todo

• email DG
• email GG - need EC30 new asic MILE without PULLY w/JST 0.8mm 12 pin cable.
• STAR MARKET - thyme packets,
• order flex cables
• make PCBs for eddy current sense
• measure resistance on boot (incorporate into mode2)
• implement thermal model, w/updates from resistance measurement.
• incorporate JR3 into LF

• get LF potential function
• for LF, if ABS - INC encoder error, then don't drop into mode 0!
• add "text code" into the ASC output from SWIFI
• pickle with robo config to make parameter restoration easier.
