Description

For better map readability, more important cities should have larger labels. An analysis of why this is important can be found here: https://www.justinobeirne.com/google-maps-label-readability

OpenMapTiles has a rank column in the place layer that can be used for the functionality: https://openmaptiles.org/schema/#place

This can be implemented in a manner similar to how we set the capital and city labels: https://github.com/osm-americana/openstreetmap-americana/blob/main/style/layer/place.js#L19-L27

Contributor guide

Research direction
Study the existing capital and city label implementation in style/layer/place.js, then inspect OpenMapTiles place layer schema to understand the rank column. Implement rank based label sizing similar to the existing pattern.
