Update documentation to reflect how to get different styles/themes

[dbdean]

Currently the README points to other repositories to get the more labels and no labels styles, but those repositories say they aren't maintained, and point me back here.

I gather from poking around in the code that the different styles can be chosen by changing the themes/label-XX.yaml file that is imported at the top of cinnabar-style.yaml, where 0 is less details, and 11 is the most?

Can the documentation in the README (and elsewhere as appropriate, I guess) be updated to reflect how the different label styles are supposed to be chosen. If my guess above is correct, it would also be nice if the label-XX.yaml files were named to better reflect the changes in each one.

Thanks!

Hi @dbdean you can read more about theme imports in the general Mapzen cartography documentation and in the original Refill blog post which introduced the concept:

• https://mapzen.com/documentation/cartography/themes/
• https://mapzen.com/blog/refill-levels-of-detail-and-labels/#label-density

Agree this repo needs to be updated to reflect the current state. Thanks for flagging that!
