transformers-compat

This package includes backported versions of types that were added to transformers in transformers-0.5 for users who need strict transformers-0.5 compatibility, but also need those types.

Those users should be able to just depend on transformers >= 0.5 and transformers-compat >= 0.7.3.

Note: missing methods are not supplied, but this at least permits the types to be used.
