Feat/issue 102/handle idle sleep mode

[Asanto32]

Support to handle the idle_sleep_mode for Actigraph watches. This function fills in time gaps in the data created by enabling idle_sleep_mode. In cases when the samples are not linearly spaced within one second, the data is resampled.

This is ready for review now. Small chance of merge conflicts with the orchestrator compared to the new one with full directory processing but I tried to make sure it should work together.

Note: when there are significant amounts of idle_sleep_mode gaps it does slow down processing. Not due to the idle_sleep_mode_imputation (which only takes 5-10s), but from the addition of significantly more data points (example test case on my computer adds in more than 50% of the data thus increase in processing time by ~50%)
