Implement PDU 24A

[bjackson312006]

Changes

• pdu.c: Added current reading for the 4 current sensors. Set up each sensor in init_pdu. Updated pinout.
• pdu.h: Made changes to reflect current sensing additions in pdu.c. Also updated enums to reflect what is currently on the Altium schematic.
• monitor.c: Added a function to read the 4 currents and send a single CAN message with the readings. Called this function in vNonFunctionalDataCollection
• fault.h: Added a fault code for current
• cerberus_conf.h: Added a CAN ID for the current message
• Makefile: Added INA226.c (current sensor driver)

To Do

• Update pca9539 --> tca9539 - (Not doing this until before merge)
• Add a current sensor read command x4 and send over CAN, corresponding YAML
• Update pinout according to schematic.
• Update fuse and shutdown extraction and repackaging as bools in YAML, use correct pins (note: low refresh rate)
• Update PDU CTRL functions to correct pins.
• Update PDU TSMS sense to correct pins
• Update driver interaction layer as needed

Didnt look over actual pins yet but the overall structure is great!

Looks good, a few trivial things. This thing is going to have to sit on back burner until the board is ready. Super awesome job:)
