Bug: FileNotFoundError: 'VERSION' is back when building during a pip install

Describe the bug

pip installing from Pypi fails to build a wheel with FileNotFoundError: [Errno 2] No such file or directory: 'VERSION'

This was an issue before, see #150. After some refactoring we're left with no VERSION file again and started reading it again in version 5.6.0 (see commit 885e930877a4e0570224298ab1c2b2997897a7d5).

As a workaround, installing 5.5.1 works as expected. Another option is to clone the repo and pip install ..

Steps to reproduce

In an environment that can't install a wheel, here Centos 7/Python 3.9/glibc 2.17.

$ pip install simsimd
Collecting simsimd

  note: This error originates from a subprocess, and is likely not a problem with pip.
