CW222222+22 python decode reject but C and google maps say 70,180

The Python version of decode treats some edge cases
differently from other implementations, for example C and google maps.

For example openlocationcode.py olc.decode('CW222222+22') gives
~/.local/lib/python3.11/site-packages/openlocationcode/openlocationcode.py", line 341, in decode
raise ValueError(
ValueError: Passed Open Location Code is not a valid full code - CW222222+22

Whereas C:
with argv[1] as CW222222+22
OLC_CodeArea code_area;
OLC_Decode(argv[1], 0, &code_area);
printf("%.18f,%.18f\n",code_area.lo.lat, code_area.lo.lon);
gives: 70.000000000000000000,180.000000000000000000

Similarly google maps accepts CW222222+22
(and appears to convert it to C2222222+22)

Python 3.11.5
gcc version 11.5.0
Linux Rocky 9

google maps Ubuntu Firefox 149.0.2
