uproot.model.classname_decode(encoded_classname)

  Converts a Python (encoded) classname, such as `Model_Some_3a3a_Thing` into a C++ (decoded) classname, such as `Some::Thing`.

  C++ classnames can include namespace delimiters (`::`) and template arguments (`<` and `>`), which have to be translated into `[A-Za-z_][A-Za-z0-9_]*` for Python. Non-conforming characters and also underscores are translated to their hexadecimal equivalents and surrounded by underscores. Additionally, Python models of C++ classes are prepended with `Model_` (or `Unknown_` if a streamer isn’t found).
