Uses MapBox

Tagging this as using MapBox before switching over to OpenStreetMap

Add ability to specify "amenity" type (pub, cafe, ...)

Add the "?amenity=pub" to the end of the URL to restrict amenity type to pub (or cafe, bar, restaurant).

Amenity incorporated into the primary key

• Adding "amenity" as second component of the PK
• Refining data to only include rows (a) which have a relevant "amenity" value and (b) are located in one of the locales used by the demo
• Updates to the Docker image to reflect this

Initial version

• Works in K8s, shows the CockroachDB operator
• Small data set so the data loads quickly in the demo
• Tested on Chrome, but doesn't yet work in Safari
