chdb support

Hello @roman-boiko

Thanks for sharing this example. This runner seems to execute clickhouse-local using the classic pipe mechanism and nodejs exec.

In contrast [chdb](https://chdb.io) supports in-process / library based execution of ClickHouse in python and nodejs (amongst other runtimes) with several optimizations on the memory and startup time front for session queries without giving up any feature.

Would there be any interest in an alternative version of this example using chdb/python instead of clickhouse-local/node?
We have a [python based lambda](https://github.com/chdb-io/chdb-lambda) example available in development.

Thanks!
