Subject: [PATCH] Bitstamp: Fix websocket orderbook snapshot blanking
 LastUpdate (#1319)

* Bitstamp: Fix orderbook snapshot blanking LastUpdate

Drive-By: Remove:
`Bitstamp BTC/USDT spot orderbook has zero bid price, filtering.`
It's unactionable and happens every snapshot right now

* Bitstamp: Use ob timestamps for LastUpdate

Obviously.
