Add arm64 cbc library to complement x86_64

[knutster]

Describe the bug
The arm64 (aarch64) server architecture is becoming more commonplace yet python-mip doesn't not work on these architectures.

To Reproduce
Try to run a model on aarch64.

Expected behavior
The model is parsed and run.

Error received

An error occurred while loading the CBC library:

Additionally, ctypes.util.find_library() did not manage to locate a library called '/usr/local/lib/python3.10/site-packages/mip/libraries/cbc-c-linux-x86-64.so'
