Make the payout process easier

[phutchins]

Scope: Make payouts easy enough for someone outside of the dGitcoin workstream to run via command line.

UX
$ yarn payouts:generate-payout-data
(ask for necessary data to generate payout data) (current steps are documented here:
https://github.com/dcgtc/dgrants/blob/main/contracts/tasks/payout-data/poc.data.ts)

• This outputs a file containing the payout data in the format (poc.data.ts) that the payout script
  (https://github.com/dcgtc/dgrants/blob/main/contracts/tasks/execute-payouts.ts) can use
  $ yarn payouts:run-test
• This should test the payout process in a locally forked network using hardhat to ensure that things will go well
  $ yarn payouts:run
• This should run the production payouts

Gotchas

• The current code that generates the payout data can only be used in the frontend and the payout data is to be copied from the console logs
• The first time you run the payout generation script, you need to copy the merkle root out of the console.log then copy that back into the poc.data.ts, then run again to verify payouts
• In order to get the console logs to show up you will potentially have to clear the indexdb in your browser and hard reload
• You must have the DEPLOY_PRIVATE_KEY configured in the contracts/.env file and it must be the private key that was used to deploy the grant round in order to execute payouts
