binance: add watchTickers

[sc0Vu]

In this PR, I made these changes:

• Add watchTickers in binance.
• Add miniTicker in binance.

Test command:

 node examples/js/cli binance watchTickers '["ETH/USDT"]' '{"name":"!ticker"}'
 node examples/js/cli binance watchTickers '["ETH/USDT"]' '{"name":"!miniTicker"}'
 node examples/js/cli binance watchTickers 'undefined' '{"name":"!ticker"}'
 node examples/js/cli binance watchTickers 'undefined' '{"name":"!miniTicker"}'
 node examples/js/cli binance watchTicker ETH/USDT '{"name":"miniTicker"}'
 node examples/js/cli binance watchTicker ETH/USDT '{"name":"ticker"}'

@sc0Vu I think we need to apply the same logic as we have in Cex, because, for futures Binance does not send all the updates within the same message, so we end up returning an empty array when the message does not contain the subscribed symbol

[sc0Vu]

It seems the topic and data format are the same for different types, probably need to wait the ticker.

These command worked for me:

node examples/js/cli binanceusdm watchTickers '["MATIC/BUSD"]'
node examples/js/cli binanceusdm watchTickers '["APT/BUSD"]'

[carlosmiei]

@sc0Vu what do you mean by "probably need to wait the ticker." ?

[sc0Vu]

@carlosmiei I see, you mean user might get empty array in this case.

[carlosmiei]

@sc0Vu yeah but as I said cex solves this issue in an easy way, can you check it out?

[carlosmiei]

@sc0Vu is this ready to be reviewed again?

LGTM ✅

@sc0Vu do you have plans for adding watchTickers for coinbase (advanced api) too?
https://docs.cloud.coinbase.com/advanced-trade-api/docs/ws-channels#ticker-batch-channel
I think coinbase might be more priority compared to other secondary exchanges (i.e. cex-io, etc..)
