/fundingInfo endpoint not supported

[lautaromss]

There is an endpoint on Binance's API, GET /fapi/v1/fundingInfo, which doesn't seem to be a function in the connector to use that endpoint.

The endpoint can be found in Binance docs: https://binance-docs.github.io/apidocs/futures/en/#get-funding-rate-info

You can retrieve data from that endpoint by simply going to: https://fapi.binance.com/fapi/v1/fundingInfo
