  CAS-14201 : Add check for mask validity
  If a mask is provided to `tclean(niter=0)` it now checks for the
  existence _and_ validity of a mask image on disk. This fixes a bug where
  a string/textfile passed into the `mask` parameter of tclean would
  trigger it to try and open the mask with `ia.open`.
  
  Now if the mask image is not present on disk, it gracefully fails.
  
  Note that at this point it is not desirable to change the behaviour of
  tclean(niter=0) to create a mask if none is present on the disk.
