    Spectrums/Images captured using splicco's automatic data capture/timed
    sequential function are automatically given a user defined file name and

    splitting the file name into sections, reversing the order and splitting
    the time stamp at 'h' 'm' and 's' then converting to seconds.

    seconds, concatenates this with the original file name, and saves the
    original data out with a new file name as a numpy array.
