CryptoYa: Exclude Binance

[alvasw]

Our Binance price provider gets the exchange rate from Binance already.

Based on #30.

Binance is providing an ARS blue rate (since 2023-06-20 apparently). Then it is getting transformed to approx 2x by the BlueRateTransformer. Is the solution enough to mark Binance as implements BlueRateProvider ?

INFO  b.p.s.p.Binance: BTC/ARS: 1.9447208E7
INFO  b.p.s.ExchangeRateService: ARS transformed from 1.9447208E7 to 3.8947405667574935E7

If the provider is a BlueRateProvider, can we return Optional.empty() instead of the source rate in order to not get the log entries about transforming a rate which is not transformed?

I tested :+1: with the 2 suggested changes above. Would be good to get them included @alvasw.

[alvasw]

I created opened a new PR (#32) in which I mark Binance as BlueRateProvider and only log the transformed exchange rates.
