#696 closed defect (fixed)

When reading U16 data, the keywords BZERO/BSCALE are put into the metadata

Description

When reading U16 data with psFitsReadImage, the BSCALE/BZERO values are correctly applied
to the data, but they are then _also_ put into the metadata. If the image is then displayed
using a fits viewer, the scale factors are applied again.

The standard keys (e.g. SIMPLE, NAXIS) are also preserved; all should be removed.

David, let me know if it doesn't make sense to assign this one to you.

psFitsWriteHeader now blocks several keywords from being written: "SIMPLE",
"XTENSION", "BITPIX", "NAXIS", "EXTNAME", "BSCALE", "BZERO", "TFIELDS".
It also blocks keywords that start with "NAXIS", "TTYPE", "TFORM" (with the aim
of blocking NAXIS1, NAXIS2, etc, but will also block NAXISABC).
