Add OceanicJS Support

[TheMonDon]

Is your feature request related to a problem? Please describe.
Not exactly, just that discord.js is hard coded for stuff like intent checking.

Describe the solution you'd like I would like to see OceanicJS support added, it is sort of a fork with Eris but is actively maintained. https://github.com/OceanicJS/Oceanic

Describe alternatives you've considered
Not using OceanicJS, but I was wanting to try and convert from discord.js.
