CPUSet for Python 3

cpuset-py3 is a Python 3 compatible fork of the original cpuset library, providing functionalities to query and manipulate CPU sets (processor affinity) on Linux systems. It allows creating, modifying, and applying CPU sets to processes and threads, facilitating fine-grained control over CPU core usage. The current version is 1.0.2, and it's maintained on an as-needed basis rather than a strict release cadence.
