📦 NEW: get cpu process

[TechWiz-3]

In this PR I've added a directory called get_cpu_process

It includes:

• get_cpu_process.py which contains three functions relating to getting the information on a process.
• cpu a CLI interface for the get_cpu_process functions which has 3 commands
  1. ./cpu <process> - returns True if the process is running
  2. ./cpu --get-pid <process> - returns the process id of the specified process
  3. ./cpu --run-time <process> - returns how long the specified process has been running

Let me know what you think 👍
