[AIP-35] Idle Finance Tranches

Proposal:

Alchemix will incentivize IDLE voters to vote for alUSD with a conditional purchase of IDLE should alUSD place in the top 5. We would use this IDLE to direct IDLE gauge rewards to the alUSD senior tranche.

Options:

Contingent on alUSD being selected to be the next Senior Tranche, Alchemix DAO will purchase the following amount of $IDLE on the open market:

1. $5k
2. $10k
3. $20k
4. Do nothing.

This vote is using Ranked Choice Voting, so please rank these options from best to worst.
