Depth Issue

[birimkulov951]

Hello Silva!

First thank you for your amazing work.

I have a issue with depth. Depth web-socket disconnects sometimes by itself how can i fix it?
And how can we add new depth future (added in 2019-03-1 change log) to your library?

CHANGELOG for Binance's API (2019-03-12)
Websocket streams
@Depth and @Depthx streams no longer have the ignored and empty [].

Best wishes!
