[OpenBabel-scripting] cast needed for OBChiralData in Python bindings

[Beda K. <Bed...@vs...>]

Hello,

I would like to use python bindings to opanbabel to access
stereochemical information stored in OBChiralData.
Unfortunately what I get from the atom by using GetData() is an
OBGenericData type object, which should be cast to OBChiralData in order
to work properly.
Would it be possible to add a conversion function to the bindings,
similarly to the toPairData() and toUnitCell() functions?

Best regards

	Beda
