Adding PHPUnit Tests for Discord Cryptocurrency Bot Regarding th

Unit tests are still one of the most effective ways to ensure the existing features not broken due to new code changes/commits. The Discord cryptocurrency bots have been observed broken when it came to NGN currency because the NGN is relatively small compared to USD which causes some rounding issues and also it is not supported in some exchanges (via API support).

I have added the tests (via PHPUnit) to make sure that these crypto conversions are always working – when new code/changes are commited. Also, I run these tests manually to make sure that I am notified as soon as it stops working e.g. due to API changes from exchanges that I do not control.
