Measurementclass
Added a Measurement class to handle data directly from the dtt files (.xml).
Added the following: pydarm/measurement.py (contains the class) examples/example_measurement.py (contains example of how to use the class) data_files/2020-01-03_H1_DARM_OLGTF_LF_SS_5to1100Hz_15min.xml (used by the example file)
It does NOT contain a unit test which is upcoming.
