[Feature Request] Add the rest of the WS2812FX effects

[cooljimy84]

Is there any plans to add more effects (all of them) from the library https://github.com/kitesurfer1404/WS2812FX that you have started using ?

Wrong repo, please post this issue here: https://github.com/OttoWinter/esphomelib

And no, I don't have any plans to add them at this point. I don't use these addressable lights myself so it isn't a priority of mine. Plus it'd need to wait for esphome/esphome-core#243 to be ready

I'd be happy to accept PRs that add more effects though.
