refactor: Remove HybridRLE iter / batch nested parquet decoding

[coastalwhite]

This PR again removes a lot of unused code and finally fully removes the
HybridRleDecoder Iterator implementation. This is done by batching the work
done with nested decoders.

This also solves a small bug that existed for nested boolean values with a lot
of nulls.
