radii calculated wrong is ISIS3

[thare]

Not sure how I missed this but the ISIS3 reader is applying a 1000.0 offset for the radii values. By default ISIS3 holds these values correctly as meters so no mult needs to be applied.

~line 497 and 501 need to have the "* 1000.0" removed.

corrected:

    /***********   Grab SEMI-MAJOR ************/
    semi_major = 
        atof(poDS->GetKeyword( "IsisCube.Mapping.EquatorialRadius"));

    /***********   Grab semi-minor ************/
    semi_minor = 
        atof(poDS->GetKeyword( "IsisCube.Mapping.PolarRadius"));

thanks, Trent thare@…
