Summary: Keeping enums in sync between all the different bindings is tedious and error prone. Getting one of the values in the incorrect order could lead to many hours of debugging as they are passed as ints to C. This diff adds a simple python script to generate these enums for all languages. This also makes it much easier to add support for more languages in the future
