Very basic s3 parquet microbenchmark

[xcharleslin]

• 1 x 64mb parquet file
• 32 x 2mb parquet files
• Column pruning vs whole file

Data in s3://daft-public-data/test_fixtures so microbenchmark can be run from anywhere.

@clarkzinzow you can run these with something like:

pytest tests/benchmarks/test_file_read.py -k parquet --benchmark-only
