Improved Auto Download for P2Pool and XMRig
Hello! 
I appreciate the great work on the project, which runs seamlessly on Ubuntu 22.04. However, I believe there is room for improvement in terms of the setup process for P2Pool and XMRig. Specifically, I suggest implementing an auto-download feature that retrieves and installs the latest versions of P2Pool and XMRig for the user.

For Windows, consider using the "Local" directory, and for Ubuntu, the "~/.gupax" directory can be used.

I hope this feature suggestion aligns with your vision for the project. If you agree I can start working on PR
