Current Behavior
Currently TheGraphFetcher only queries SpotEntry from Uniswap V3.
Expected Behavior
TheGraph should be abstracted away and we should be able to create fetchers that inherit from a base TheGraphFetcher class and easily decide what data to fetch Spot/Future/Generic, which subgraph to use, which data to query..
A PR that solves this issue should create a UniswapV2Fetcher and UniswapV3Fetcher to demonstrate the work.
