    Fits: initialized ndim variable in new pixelareaarcsec2
    
    Until now, the 'ndim' variable in the newly added function to calculate the
    pixel area in arcsec-squared wasn't initialized (to zero). This was not a
    problem because the value will be written in later. However, some compilers
    printed an "used uninitialized in this function [-Wmaybe-uninitialized]"
    warning.
    
    With this commit, to avoid this wrong warning, the value has been
    initalized.
    
    This issue was reported by Faezeh Bijarchian.
