Add '-e, --extract-artwork' operation

[ ADDED ]  New operation '-e, --extract-artwork'.  By default, this
           operation extracts any and all types of artwork embedded
           inside FLAC files into a directory with with the same name
           as the FLAC file (with a unique name appended).  This is
           useful to save all the artwork before removing it via the
           '-p, --prune' operation
