Lets you find multiple datasets at once assuming they have a 
    filename which contains a pattern of the form:
    CH<ChannelNo>_RUN00...<RunNo>_REPEAT00...<RepeatNo>    

    Parameters
    ----------
    Channel : int
        The channel you want to load
    RunNos : sequence
        Sequence of run numbers you want to load
    RepeatNos : sequence
        Sequence of repeat numbers you want to load
    directoryPath : string, optional
        The path to the directory housing the data
        The default is the current directory

    Returns
    -------
    Data_filepaths : list
        A list containing the filepaths to the matching files
