Reconciled with block: Uplinkin Sol 141

Objectives:

Measure the composition of the atmosphere with special emphasis on CO2 isotopes. We will measure the atmosphere via the TA Sample inlet, Cal Gas via the TA Sample inlet, and then finally atmosphere via both inlets.

Configuration:

The carrier valve is not too reliable, but it will not be used here. Just in case, we will open and close valves with multiple commands.

Software updates were made post Sol 113 to the 386SW and the mode table was changed to V125

Note: Step 55 can be reduced to 5 mins, Step 57 can be reduced to 5 minutes if total duration is a problem for power.
