Description

Right now CurrencyConverter.convert() is just a stub to give a result that is almost always completely wrong. The whole thing needs to be built from the ground up. Choose a publicly available API to obtain current exchange rates, and maybe a different API to test against (a variance of up to 10 cents is acceptable).

If you take up this issue, don't change CurrencyConverterTest. You may create a separate test class, and if I accept your pull request I will make a new Hacktoberfest issue to merge your tests into CurrencyConverterTest.

Contributor guide

Research direction
Find a publicly available API for current exchange rates, implement the CurrencyConverter.convert() method to fetch rates and compute the conversion, ensuring accuracy within 10 cents. Consider using a different API for verification. Do not modify CurrencyConverterTest.
