   2. For each event, it emits a log message
   3. A tool (e.g. Kafkatorio Kafka Pipe) reads the logs, and sends the messages to a Kafka cluster
2. Kafkatorio Events Server reads the messages from Kafka

todo

• add settings
  • is active - whether files are exported or not
  • delete files - clean up all files
  • tick-rate - how often reports are generated
    • requires on some sort of in-mod cache of map<entity-id, event>
    • also divide by game-speed? to keep ratio the same
• Move to a vector tile supported map. PNGs are slow.
  • Maplibre GL JS? https://maplibre.org/maplibre-gl-js-docs/example/
  • Add VectorGrid? https://leaflet.github.io/Leaflet.VectorGrid/vectorgrid-api-docs.html
