Going from Python 3.9.7 to 3.9.8 function _PyUnicode_DecodeUnicodeEscape was refactored, split and renamed. Even though this was meant to be internal, it was used by packages typed_ast, and apparently also mypy. Resulting in, for example:
Python 3.9.11 (main, Mar 28 2022, 10:10:35)
[GCC 7.5.0] :: Anaconda, Inc. on linux

Since we moved from 3.9.7 to 3.9.11 we're hitting this problem. This patch adds back the symbol.
