Translation Command

[LeoSaucedo]

The next feature we are looking to implement is a translation command. However, we have several constraints:

• The feature must be free, or limited, and throw an error if we hit the limit instead of billing.
• The feature must either include an asynchronous API, or have a REST API we can query using aiohttp.

Implementation usage and features are left to be decided by the assigne. In the past, the ;translate feature was limited to interpreting the argument's message and translating it to English. It does not have to be the same in this implementation.
