How ParquetSharp handle legacy parquet files

[Mydurian]

Hi Team,
When referring the Apache official doc for complex logical type.. I see that the structure definition is somewhere different. Could you help elaborate a little bit more on how to handle some backward-compatibility in ParquetSharp? Thanks in advance.

Hi @Mydurian, ParquetSharp doesn't depend on the names of schema nodes matching the specification, following the backward-compatibility rules, but we currently only support lists that are represented with the three level structure and don't handle data that is missing the inner element layer.

I don't think there's a simple way to work around this, but we'd be open to accepting a pull request to add backwards-compatibility support for reading files that don't use the standard schema structure.
