Use PyUnicode_DecodeUnicodeEscape directly

Thanks! In general, I think typed-ast tries to avoid changes to the original source. See my comment on #171 (comment) , I think this only results in different, but slightly more consistent behaviour across Python versions in a situation in which probably no one will ever use typed-ast (and in which typed-ast is already inconsistent across Python versions). So not sure whether this is worth it.

Let me know what you think and then I'll make a release accordingly.

By now, I don't think we need to stay close to the original code, since that is dead anyway. I believe that this change could avoid problems when _PyUnicode_DecodeUnicodeEscape is defined by Python (as it obviously was prior to the latest 3.9 release).
