+  "ycbcr" profile will raise a "DeprecationWarning" (#44)
+- "webp" profile has been added to COG profiles. Exploitation of this new

+- Rio-cogeo can calculate the overview level based on the internal tile size

Rename `YCbCR` profile to `JPEG`
https://github.com/mapbox/rio-cogeo/blob/dc48a99b23fa1c538cb8b81747c5217fc1f996b7/rio_cogeo/profiles.py#L6

I think using `jpeg` instead of `ycbcr` will make more sense for a profile name
