FEATURE: [binance] add margin request

[bailantaotao]

1. The go-binance library has been deprecated, so I added a new margin request.
2. We don't need the timestamp because the value is initialized in client.go

use fixedpoint value?

[bailantaotao]

OK.

The previous type is because I simply copied the value from another file.
The caller uses req.Price(order.Market.FormatPrice(order.Price))

Re-estimated karma: this pull request may get 566 BBG
