Default to master branch (user can override with an argument), update the repo if we find a git folder but no venv folder (indicating blank env), rename BASE_DIR to PARENT_DIR to be more obvious, enable PARENT_DIR to account for an arbitrary amount of folders.
Changed runpod detection to a variable to simplify maintenance and provide a mechanism for the user to force a runpod installation. Also, updated help message to acount for the change.
Script now accepts long and short arguments. Script should now help with a runpod environment and ensure apt cache is updated before package install attempt.
Linux distribution detection is much more robust. We also now include the Linux distribution family. That should help downstream Linux distributions as well. For example, Manjaro will now be detected as arch and Mint Linux will be detected as Ubuntu.
Install scripts have been consolidated for every non-Windows OS. Python Requirements were consolidated. README improved to work locally and provide more information.
