Began adding functionality to allow peaks of interest to be manually selected rather than automatically found.
Added values to RunConfig structure: array to store channels for which manually peak select has been requested.  bool to record if manual should be used as a fallback if auto fails.
Read channels to use this feature from command line using -mp option
Passed correct value for each channel into fit options.

Now need to implement it in the fit code itself....
Manual peak selection now working.
Still some fine tuning required regarding ease of use e.g. swapping control between plot and temrinal.
Added 133Ba to source options for calibration.
