Store Calibration Data in the Raw Data File

[tmolteno]

The current state of the calibration data should be stored in the raw data file when it is gathered. Otherwise the raw data files can't easily be imaged from without downloading this data via the API at the time that the data file was generated.

• Add the Antenna Positions (to the config)
• Add the current Calibration Data to the config
• Make sure the full config is in the RAW file
• Make sure the full config is in the VIS file
• Put a version into the HDF file, and check for this when loading files (to avoid trying to load calibration data if it isn't there. (Required for backward compatibility)
