Query latest price of ADA against another currency (java)

[jbax]

Need a java method that will receive a token symbol (currently only ADA) and a given target currency (USD, EUR, GBP), then return the current price of 1 ADA against 1 USD, EUR, GBP, etc.

One can easily query this using Binance for example, through the binance-java-api. The initial implementation can poll a single exchange but we must have multiple sources of truth here (so taking that from coinbase and other exchanges is a must).

This will be used so that the store owner can list the price of something like a shoe in USD, and the app will automatically update the price of that shoe in the website to display the ADA price (or in the future, the price of other tokens that run on the blockchain).

Currently working on this. If anyone wants to collaborate lmk.

If anyone wants to add more sources of prices please check package com.univocity.shopify.price.

Basically all you need to do is to create an implementation of PriceConverter. You can use class BinancePriceConverter which I adapted from @Daniel-SchaeferJ contribution (many thanks!)
