It depends on what parts of the Georeferencer you need. If you don't need
the GUI but only the math, you could consider writing a SIP wrapper
around QgsGeorefTransformInterface implementations [1].
Otherwise, if Python performance would suffice, you could grab the low
level math from QgsGeorefTransform and QgsLeastSquares [2] and translate it
to Python.
