add pancakeswap, shadow, bluefin, rocketpool (#109)

* pancakeswap

* Shadow Exchange

* remove clever because it do have emissions

* add bluefin

* add rocketpool

* rocketpool use get rocket storage instead of hardcoded so we can backfill emission data

* rocketpool abi

* fluid

* stakewise maple
