#2 falls over with "can't convert given polarization to index"

[Oleg Smirnov]

Trying to make a Stokes IQUV image -- had to poke around the code a bit to figure this out as the help string for the "-pol" parameter is still out of date -- eventually got it to accept "I,Q,U,V", but it fails towards the end:

$ wsclean -size 4096 4096 -nwlayers 128 -scale 0.00055 -weight natural -niter 0 -datacolumn DATA -channelrange 0 1 -pol I,Q,U,V 3C147-CD-LO.MS
