Description

Adds coinbase as a provider.

closes: #629

A few things to note :

  1. The "ticker" channel's response body is different than the docs specify, so this isn't restricted to using matches for tickers like I thought previously
  2. There is no candle/kline "historical data" websocket, so we'll have to create these from the trade history pushed to us by the "match" channel

Yeah, this looks pretty reasonable to me. The only other clean approach I can think of is to bucket all trades that are within 1 minute of each other (after sorting ofc).
