More tests cases to deal with affinity
...
I'm not sure how these manifest - whether SQLite retypes them based on
column affinity before we see them, or whether they're provided as is.

rowid is special since its column index is -1, so add

Fix when last rowgroup is not same size as first

...change test data to use 99 rows, so that when we have
rowgroup size 10 we exercise this code.

Add a pg oracle
...
- define `datetime`, `printf` fns in pg so it produces similar
output as sqlite
- tidy up input data to be less wide
To do: some fns to make it easy to generate a new test case. Probably
want to mount all the 3 parquets simultaneously and refer to the
sqlite table by the same name as the pg table.

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.

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.
