Review Comment:
Thanks, @etseidl.
Related to protobuf (the parquet-java binding for protobuf) this is the
other way around currently. There is a flag for converting repeated protobuf
elements to "3-level" lists but it is false by default, so it converts directly
to similar repeated elements in the parquet schema ("1-level" list).
Anyways it seems that neither parquet-rs nor parquet-java (protobuf) should
have an issue creating proper "3-level" lists.
