Correct drift rate resolution calculation
When the number of time integrations is not a power of 2, the next power of 2 was used for the number of time integrations in the drift rate resolution calculation (data_handler.py DATAH instantiation). As a result, this threw off the drift rate calculations in the doppler search main loop (find_doppler.py).
Visible symptom: the red-colored fit lines of the plots were not falling on the signal in the waterfall plots of the signal candidates.
