Removed functions still in use by pymeos

[SiggyF]

Describe the bug
I tried to install pymeos and pymeos-cffi from source but #9 has removed some functions used by pymeos (master, 07873e9).

To Reproduce
Steps to reproduce the behavior:

1. Build and install meos (master, ec66425cea46)
2. Build and install pymeos-cffi (pip install -e .)
3. Build and install pymeos (pip install -e .)
4. See error:

ImportError: cannot import name 'pg_date_in' from 'pymeos_cffi' (~/src/PyMEOS-CFFI/pymeos_cffi/__init__.py)

Expected behavior
Succesful import

Desktop (please complete the following information):

• OS: OSX
• Architecture: ARM
• Environment: pip 24.3.1
• Version: 065aa0e

Additional context
In #9 a the function pg_date_in was removed. The function is present in libmeos.dylib (nm libmeos.dylb shows symbol with T).
There are also other functions that are used in pymeos that have been removed in #9 (e.g. pgis_geography_in, pgis_geometry_in).
