Colin Dellow 0d4806ca6f Rejig parquet generation
- "fixed_size_binary" -> "binary_10"
- make null parquet use rowgroups of sie 10: first rowgroup
  has no nulls, 2nd has all null, 3rd-10th have alternating
  nulls

This is prep for making a Postgres layer to use as an oracle
for generating test cases so that we have good coverage before
implementing advanced `xBestIndex` and `xFilter` modes.
