Rationale
This PR is part of testing how much faster Parquet thrift decoding would be if we extended the APIs to skip parsing the portions that are not needed for query, specifically various statistics from the parquet footer metadata (aka column stats and encoding stats)
I do not intend to propose merging this (ever)
Contents:
It is a PR to the most recent version of the
thrift-remodelbranch from @etseidl hereparquet::formatstructures apache/arrow-rs#8476With the code for deserializing statistics disabled.
