[sqs] rank pools by spread factor

[p0mvn]

Create rank multiplier for each spread factor. The lower the spread factor, the higher the ranking for routing.

This will let pools with smaller spread factors get greater points in rankings. However, the multiplier should be an order of magnitude smaller than liquidity rank bonuses.

Liquidity is a more important metric for routing that is also inversely correlated with spread factors

Relevant function:
