 generic_dataset::clear_flags
        Clear the generic DS flags.

 Usage:
        dsref -> clear_flags[, /ready]

 Keyword:
        ready   If set, then only clear the ready flag, not the read
                flag.

 Notes: 
        This nasty piece of work is needed because spect streams can
        have their sectoring changed independantly and this needs
        flagging back to the dataset.
