A36224-000 Version 0.0.11

Set up SF6 pump control. So far, it is tested and working well. Next
steps are to figure out how to store the bottle status, and implement
override and reset commands on the ECB and gui. A strange thing is
happening with Analog 0. the input is tied to ground, but it is seeing
1.33V. Probably on the board, but I'm not sure how or why yet.
A36224-000 Version 0.0.12

Managed to make the SF6 bottle level save to program memory. Figured out
what was wrong with analog 0- it wasn't connected to anything. Added
code to allow commands to come in from ECB for SF6 related fault resets.
