the python binds with output params is difficulty to use

[mingforpc]

in dwg.i ,

etc:

EXPORT bool dwg_dynapi_header_utf8text (const Dwg_Data *restrict dwg,
                                        const char *restrict fieldname,
                                        char **restrict textp, int *isnew,
                                        Dwg_DYNAPI_field *restrict fp);

the output params is textp, isnew, fp， in LibreDWG.py

def dwg_dynapi_common_utf8text(_obj, fieldname, textp, isnew, fp):
    return _LibreDWG.dwg_dynapi_common_utf8text(_obj, fieldname, textp, isnew, fp)

I cannot call this function success， always get error

TypeError: in method 'dwg_dynapi_entity_utf8text', argument 4 of type 'char **'

I found this https://stackoverflow.com/questions/15185010/how-to-receive-reference-and-pointer-arguments-in-python-swig , it seem need some modify in dwg.i.

But I am not familiar with SWIG
