Add getTickers for #124 and #98 #520

Closed TSavo closed 4 years ago

TSavo commented 4 years ago

Per tickets #98 and #124, it's been requested to allow for a single Observable that emits multiple (or all) currency pairs. This PR enhances the StreamingMarketData interface for all exchanges to support this with a new method: getTickers(CurrencyPair ...). Just pass it all the currencyPairs you are interested in, and on supported exchanges it will filter from a single stream, otherwise it will subscribe to all the tickers listed, and return a composite Observable that emits all the pairs requested.
