When I install the latest version of gtfs_functions==2.7 and h3==4.2.2 on Python 3.11, i get the following error when I try to import.

>>> import gtfs_functions
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named 'gtfs_functions'

The only solution I've found so far is to use the following versions:

gtfs_functions==2.5
h3==3.7.7

I've tried this both on Linux (Ubuntu) and Mac (Silicon).
