Suggestion: Support Parquet-based changeset integration (e.g. osm-changesets-to-parquet)

[vizsim]

Hi,

Thanks a lot for making ohsome-planet available — it’s an super useful project!

While using it, I noticed that integrating changesets can be a bit slow and cumbersome at the moment. The current approach (--changeset-db) still relies on a JDBC connection to a local database following the ChangesetMD schema, which feels somewhat outdated and not very convenient for modern data pipelines.

I was wondering if it might make sense to support an alternative or additional method for bringing in changeset data — for example, using osm-changesets-to-parquet. This tool already outputs changesets directly as Parquet files, which could make integration faster and simpler, avoiding the need for a database step entirely.

Would you consider adding support for this, or perhaps exposing a way to plug in pre-generated changeset Parquets?

Thanks again for your work — ohsome-planet is a fantastic project and a huge contribution to the OSM ecosystem!
