missing 'includeFirst' param for get_instrument_history call

includeFirst: Optional A boolean field which may be set to “true” or “false”. If it is set to “true”, the candlestick covered by the start timestamp will be returned. If it is set to “false”, this candlestick will not be returned. This field exists so clients may easily ensure that they can poll for all candles more recent than their last received candle.

The default for includeFirst is “true” if the includeFirst parameter is not specified.
