Support DuckDB as computation backend

If I understand Kotlin dataframes correctly, computations are done directly in the JVM.
For many use-cases, the optimized data storage and vectorized computations of DuckDB could be very useful in terms of performance and memory consumption.

So maybe there could be a way to move computations to DuckDB via Apache Arrow, which offers a columnar memory format, zero-copy reads, streaming, and an extensive Java API.

The goal would be to perform analytical computations against DuckDB directly from Kotlin in a way similar to the one described here for Python and R:

Looking forward to hear what you think about the feasibility of such an approach.
