We already have a similar case with the bindings' `CXSaveError` for `clang_saveTranslationUnit` on the C side, for which we've implemented the `TranslationUnitSaveError` exception on Python side.
On the C side, we also have `CXErrorCode` for `clang_parseTranslationUnit`, `clang_reparseTranslationUnit` and `clang_createTranslationUnit`. Mirroring the `clang_saveTranslationUnit` call, there's already the `TranslationUnitLoadError` error for those 3 functions

I would thus suggest adding this to the `TranslationUnitLoadError`, rather than making a new exception for this
