Add spot support for canceling an order by oid #25
Description
Would be nice to be able to cancel spot orders
func (api *ExchangeAPI) CancelOrderByOID(coin string, orderID int64, isSpot bool) (*CancelOrderResponse, error) {
assetId := api.meta[coin].AssetId
if isSpot {
assetId += 10000
}
return api.BulkCancelOrders([]CancelOidWire{{Asset: assetId, Oid: int(orderID)}})
}
