feat: more efficient parquet writer and more statistics (delta-io#1397)
23676d0 
# Description

* Removed the data copies in a tight loop, which were extremely bad for
performance when writing files > 100MB.
* Rewrote statistics handling to collect null values from metadata, just
like min and max.
* Added support for more types in statistics.
