Implement observer with SQL query support and parquet export

Implement an F3 observer that:
* listens to F3 gossipsub messages
* collects them as long as they can be decoded as CBOR
* offers a SQL interface to query them over a HTTP
* rotates them into Parquet files
* deletes any rotated files based on a configured maximum age

Fix base image to distroless/cc because of duckdb libstdc++
dependencies.
