Orderbook

Order book feed for a currency pair.

The order-book channel generates a book event when a order is added, updated, deleted from the orderbook.

When subscribing, the pair should be set in alphanumeric format only. Do not use separators between the base and quote asset. The correct format for NIZA/USDT to be set in a channel name is NIZAUSDT.
