I noticed that process-openmaptiles.lua is not up to date with the OpenMapTiles schema.

For example here in poiTags variable

• the key amenity has 53 values whereas there are 66 values in the OMT schema
• the key office is completely absent, whereas there is 60 possible values described in OMT schema

https://github.com/openmaptiles/openmaptiles/blob/077e7627f15bda6713af6dbc5e27942ca22b06ad/layers/poi/mapping.yaml#L121

Was it intentional not to include everything? Or is it because the OMT scheme has changed since then?

In any case, I will make the changes for cartes.app. Are you interested in a PR here to get a more up-to-date version?
