Finalize runtime constants - Sampling and Detection time limits

[gavination]

Shorten initial tremor detection period if possible. The more I think about this, the less important it is to me; it seems very long compared to a 10 second treatment period but should be more reasonable it patient only does it once a day. If 20 seconds doesn’t sacrifice too much accuracy, can go to this; otherwise fine as is.

Lengthen treatment duration (60 minutes day 1, 30 minutes days 2-7)
