use new API URL

[adiabuk]

Old API URL (apiratesapi.io) seems to have been decommissioned and can no longer be resolved. A GET on the top level returns an address which works: https://exchangeratesapi.io

Hey, just thought I'd share my experience. I seem to be getting an error while using your fork:
HTTPSConnectionPool(host='exchangeratesapi.iolatest', port=443): Max retries exceeded with url: /?base=GBP&symbols=USD&rtype=fpy (Caused by NewConnectionError('<urllib3.connection.HTTPSConnection object at 0x1FF609D0>: Failed to establish a new connection: [Errno 11001] getaddrinfo failed'))

it doesn't work.

I've set the URL to "https://api.exchangeratesapi.io/api/" but the response I receive back is:

b'{\n "success": false,\n "error": {\n "code": 101,\n "type": "missing_access_key",\n "info": "You have not supplied an API Access Key. [Required format: access_key=YOUR_ACCESS_KEY]"\n }\n}\n'

I think they might have moved to a completely paid service? Their free account seems to only offer 200 requests /mo. Hope I'm missing something :/
