Update reward weights scoring criteria

If the rebalancing date is set to Jun 9th, this proposal will be implemented on that date.

The current scoring criteria was based off of the following: 45% floor price 31% liquidity 11% market cap 10% volume 3% holders

Demand and volume for uTokens and UNIC is important for the protocol. Also, making sure that the whitelisted pools continue supporting UNIC instead of dumping all to market helps move the protocol forward. Therefore, I'd like to propose an updated reward weights scoring criteria: 35% floor price 30% liquidity 22% volume 8% market cap 5% holders

On top of this, we should incentivize holding the UNIC rewards / staking into xUNIC. We can do this by calculating the amount of rewards that each pool retains (instead of selling on market) by tracking the swap transactions made by those that farmed out of specific pools (we would be able to track back transfers to other addresses and then selling through the script as well). We can calculate the % of rewards held by each pool during each 2 weeks interval between the rebalancing. This percent can be multiplied to the final allocation points for the pool.

For example, if uBOB kept 100% of his UNIC rewards, his points would remain the same. If uBOB kept just 50% of his UNIC rewards, his points for the next interval would be half of what he would receive otherwise.

This proposal will likely not be eternal. However, it bakes in incentives to support the price throughout current market conditions, until more liquidity is added and UNIC gets added to more centralized exchanges as well.
