Proposed Changes

Implement utility CLIs to:

• get the power table used by F3 at a given instance ID.
• get total proportional power of a list of actors at a given instance ID.

These utilities allow us to debug the exact participation power for an instance without having to manually calculate it or estimate it from the latest power.

It will be slightly annoying, but can you separate the commands into separate vars? The diff is hard to read because it got too wide.

can you separate the commands into separate vars?

Sure; done.

The diff looks more verbose now unfortunately.

If this is hard to review, can break up the vars in a separate PR then rebase this one. Please let me know if you'd prefer it that way @Kubuxu
