The GFitsHDU::card methods now return a reference instead of a pointer. Some more methods have been added to GFitsHDU for header card access and management. The fits_key_not_found exception has been removed, and keyword checks are now done using the hascard() methods. This was needed as the GFitsHeader class does not throw the fits_key_not_found exception anymore if a header card is not found. The FITS utility function gammalib::fits_move_to_hdu has been added to the GFits.hpp/cpp files which provides support for moving to a specific HDU. As this cfitsio function is widely used in the FITS module it was favourable to put it in a specific function with a generic exception message.

… the header file as inline methods. During the rework, a bug occured in the string column class that prevented from correct saving to the file. The bug was due to the fact that the wrong pointer was specified by the ptr_data() method, and then, also the GFitsTableCol::isloaded() method that worked on ptr_data() was not corrected. The ptr_data() method has been corrected for the string column class and the isloaded() method has been defined as pure virtual in GFitsTableCol, and now is implemented in the derived classes. We thus have full control over the definition of the loading state. To conform to the actual coding standards, all methods that are implemented by the table column classes in the header file are now declared inline.

It is recommended to pass all arguments to exceptions by reference to avoid memory allocation during exception throwing.

Add an optional message to the rsp_invalid_type exception.
