* Expose type annotations

- Construct tuple directly instead of using Py_BuildValue.
- Return a tuple of tuples instead of a list of tuples.
- Read argument (fd) directly instead of using PyArg_ParseTuple.

Header files passed to genecodes_c.py were ignored after commit 4a0efdd2.

Update to upstream version '1.8.0'
with Debian dir c8008f066f1157d3a0b41ed003648d5b90a1009c

- The existing ecodes.py is renamed to ecodes_runtime.py.

- An ecodes.py is generated at build time (in build_ext) with the genecodes_py.py
  script, after the extension modules are built. The script essentially does a
  repr() on vars(ecodes_runtime) and adds type annotations.

- If something goes wrong in the process of generating ecodes.py, ecodes_runtime.py
  is copied to ecodes.py.

- Stop generating ecodes.pyi as the generated ecodes.py is fully annotated.
