/**
 * Binance now (as of Nov 2019) has the ability to perform live subscribes using
 * a single socket. With this functionality, there is no longer a need to
 * use the URL-mutation code and we can use a BasicClient and allow subscribing
 * and unsubscribing.
 *
 * Binance allows subscribing to many streams at the same time, however there is
 * a max payload length that cannot be exceeded. This requires the use of a
 * subscription batching method.
 *
 * Binance limits the number of messages that can be sent as well so throttling
 * of batched sends must be performed.
 *
 * _sendSubTrades calls _batchSub
 * _batchSub uses the `batch` flow control helper to batch all calls on the
 *    same tick into a single call
 * _batchSub calls _sendMessage
 * _sendMessage uses the `throttle` flow controler helper to limit calls to
 *    1 per second
 *
