Crash when instantiating a Model class

[Mark531]

Describe the bug
I've just installed python-mip and instantiating a Model class with no parameter causes a crash.

To Reproduce
Executing this code:

from mip import Model

m = Model()

produces this error and triggers a python kernel restart:

Windows fatal exception: access violation

Expected behavior
Instantiating a Model class should not produce any error.

Desktop (please complete the following information):

• Operating System, version: Windows 10, version 22H2
• Python version: 3.12.0
• Python-MIP version (we recommend you to test with the latest version): 1.14.2

Additional context
Executed within a Spyder IDE.

I also faced to similar problem with exactly same code.

• OS: Windows 11, 23H2
• Python version: 3.12.4
• Python-MIP version: 1.15.0
• Python and packages are managed by uv
• IDE: VSCode

When executed by debug mode, it crushed at cbc.py

cbclib = ffi.dlopen(libfile)

I think this is due to that cffi v1.15.1 installed with mip does not support Python 3.12.
According to the cffi documentation, support for Python 3.12 is started from v1.16.0.

However, I could not update cffi to v1.16.0 because mip=1.15.0 depends on cffi>=1.15.dev0,<1.16.dev0.
