Add more details about project in README

[pscott]

This PR adds details in the README, mainly by giving an overview of the flow and the different modules of Snapshot X.
It also renames voting_period to voting_duration which better represents the variable.

How "duration" is better than "period"? I've used period cuz its how it's called on Compound governor, I'd prefer if we follow same naming.

When we talked about it on Discord the other day we all agreed that duration made more sense than period. The only reason we'd keep period would be to "follow the compound standard" but since we're building some different tools, I'm not sure we should stick to their naming IF we find a better naming solution :) wdyt?

yeah i agree that keeping to a convention isnt that important here, not too bothered either way though
