Add funding rates params

[julienkermarec]

To have funding rates history of an unique coin, i want to add the future param :

    getFundingRates(futureName) {
        console.log('getFundingRates', futureName);
        if (futureName === null) {
            return this.requestWrapper.get('funding_rates');
        } else {
            return this.requestWrapper.get(`funding_rates?future=${futureName}`);
        }
    }

Thanks for pointing out the missing params! Fixed in v1.1.10, should be available shortly one the build passes.

getFundingRates(params?: {
    future?: string;
    start_time?: number;
    end_time?: number;
  })
