Modify offshoot clean for EPA

[NathanJesudason]

Describe the feature you'd like
EPA needs an offshoot clean state that fully clears everything, Riley and Kai are discussing the exact method for this.

[NathanJesudason]

First step is confirming the code version that EPA uses, the second step is then modifying the task procedure for that version based on Riley's and Kai's recommendation

[princeri1]

The EPA has given the following Requirements:

1. Fully clear the inlet line of water between runs

It is estimated that the following changes to the code will have the ideal effect:

Branch: MasterV3

1. Change the time for the AirFlush State's time variable from 15 to 60 seconds

Please msg me when completed and I will conduct testing on the v2 Sampler
