Need a set benchmarks for evaluating performance implications of parquet
predicate pushdown. This sets up some very basic benchmarks which can be used
for that purpose. Thanks to @tustvold for cooking up a script to generate
synthetic datasets for this purpose.
# What changes are included in this PR?
<!--
There is no need to duplicate the description in the issue here but it is
sometimes worth providing a summary of the individual changes in this PR.
-->
Add new benchmark script `parquet_filter_pushdown` which will execute a
series of `ParquetExec` plans with different filter predicates. For each
predicate in the suite, we will execute the plan with all three different
`ParquetScanOptions` configurations:
1. Disable filter pushdown entirely (currently the default behavior)
2. Enable filter pushdown and predicate reordering
3. Enable filter pushdown without predicate reordering.
# Are there any user-facing changes?

No
