Implement FIX API

[mauricioschenkel]

Thanks again for everyone that worked on this library. It is helping me a lot to save time and focus on trading logic.

It would be nice to implement the FIX API, as it is the suggested way by Binance to interact with orders in spot market.

Documentation for FIX API:
https://developers.binance.com/docs/binance-spot-api-docs/fix-api

You can find the Binance recomendation on Order Update User Stream documentation:

If you have the time and opportunity to implement this, I would greatly appreciate it. @mauricioschenkel

@xyq-c-cpp I'll probably need it on my project, so I'll try to implement it.

Currently I don't have too much time, but I think I'll be able to work on it soon.

I'll check later if one of these libraries can help us to save time on this implementation:

If you have any restriction to use libraries like this on the project, please let me know
