Add support for quoteOrderQty field for NewOrder message

[netomi]

According to the official changelog for the binance api

https://github.com/binance-exchange/binance-official-api-docs/blob/master/CHANGELOG.md

the field quoteOrderQty should be enabled for all symbols. If supported for binance dex (I am not 100% sure of this), it would be great if the java sdk could support that as well. I tried to add it myself, but the messages are serialized with amino and I am not aware of the fieldnumber for this new field (see dex.proto). Could you give some insights on this? Is the field supported for binance dex as well?

Supporting the quoteOrderQty would be great as currently there is no easy way to sell a fixed amount of a quote asset.
