Remove SCRIPT_DIR and default config location to user home

[MonkeyCanCode]

This PR remove the use/needed of SCRIPT_DIR and change the default config location to user home (~/.polaris/)

IIRC I used the home directory in an earlier version of the CLI, but this caused issues with multiple Polaris environments conflicting. Keeping the venv and everything within the Polaris directory actually seems like a good thing to me, what do we gain by using home instead?

I think the problem with Polaris directory is for users who only want to use CLI and not downloading the entire code base, there won't be a repo path for them to use. Maybe we can allow users to specify where to put as an overwrite?

+1 to allowing a custom location, good idea. We could also default to something like ~/.local/lib or /usr/local/ if you think that's better than SCRIPT_DIR as a default.

Sounds good. Let me draft something later this week then ask for review again. Thanks.

@eric-maynard do you mind take another look?
