Add new states to UI

[NathanJesudason]

Describe the feature/problem

Currently the prefilter clear state, the depressure state, and the intake dry states aren't displayed on the UI. Also, the user can't modify the time for the prefilter clear state and the intake dry state. See OPEnSLab-OSU/ednaServer#66

Describe the solution you'd like
For task editing, add input for prefilter clear and intake dry state times. For the monitoring page, add all three stages into the list so that when the sampler is in that state, it is displayed on the UI.

Describe alternatives you've considered
One day, we should set up the monitoring page to get the list of states in a procedure for sampling. That way, the UI won't have to change everytime the sample procedure is changed. Additionally, it would be really cool if we could one day program procedures for sampling on the UI and then have the sampler run that, but that is much more complicated than what is needed here.
