[fitsbits] WCS keywords in tables

[Bob Garwood]

Note that in the SDFITS convention, to sort of answer a previous 
question on this thread, that the WCS construct in the table is assumed 
to apply  to the DATA column and may also apply to any additional column 
having a TMATXn keyword associated with that column (column n) where 
that keyword should have a value of TRUE.
