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.

Rename some references to CSVs
...
...some nonsensical things, like "first row of Parquet",
but we'll tidy them up later.

Initial checkin of CSV table
...
parquet.cc is a fork of the sample CSV virtual table at
https://www.sqlite.org/src/artifact?ci=trunk&filename=ext/misc/csv.c
So far the only changes are those needed to make it compile cleanly in
C++11 mode.
