   Load frequency ramping data from source file

   Parses a file containing frequency ramping data, and loads the part of its
   contents that falls within a specified range of dates into a dictionary.

   :param ramping_file: Path to the source file for ramping data
   :param ramping_type: Whether the file contains one-way or three-way data.
   :param time_interval: Time interval from which data is wanted. If not set,
   the whole content of the source file will be loaded.
   :return ramping_data: A dictionary containing the ramping data between
   specified epochs. For one-way ramping, the dictionary contains a Time object
   with the beginning of coverage for each line (t0), a Time object with the
   end of coverage for each line (t1), an array with reference frequencies (f0),
   and an array with derivatives of frequency during coverage (df). For
   three-way ramping, it contains an additional entry with the name of the
   uplink station for each line (uplink).
