733	psFitsHeaderValidate defined too restrictive.	robert.desonia@…	Paul Price	"The function psFitsHeaderValidate is defined and implemented too restrictively.  

First, limiting keywords to  8 characters and to be only uppercase, 0-9, or underscore is not required if 
the HIERARCH keyword extension is used.  

Furthermore, requiring that the 'missing' keywords be added is just not very useful as nothing in the 
psLib library requires them to exist in the psMetadata header.  it is truly best for the particular write 
routines to add the keywords as required given the size of the image, table elements, or whatever the 
case may be.  Even the 'SIMPLE' keyword is of no use as that is automatically inserted as well in the 
write/insert routines and all it does in the psMetadata structure is consume memory.

The function's only real added value is to scan the items of the psMetadata for datatypes not able to be 
represented in the header.
