Write an array of values to a column in the current FITS HDU.
The column number may refer to a real column in an ASCII or binary table,
or it may refer to a virtual column in a 1 or more grouped FITS primary
array. FITSIO treats a primary array as a binary table
with 2 vector columns: the first column contains the group parameters (often
with length = 0) and the second column contains the array of image pixels.
Each row of the table represents a group in the case of multigroup FITS
images.
The input array of values will be converted to the datatype of the column
and will be inverse-scaled by the FITS TSCALn and TZEROn values if necessary.
