Add Sushiswap connector to the gateway:
https://app.sushi.com/swap
- The Sushiswap sdk is similar to the Uniswap sdk.
- Created the Sushiswap connector and made it usable via amm routes.
- Add a function for fetching pair data in the connector to replace the Fetcher class that was removed from the sdk.
