These files are a subset of the zsv CSV parser, vendored unmodified except
for the patches listed in src/vendor/zsv/UPSTREAM, which also records the
exact upstream commit. Only the parser library is included; the zsv
command-line application and its SQL, SQLite, JSON and extension facilities
are not part of this package.

The CSV fixtures and their expected parse results in that file are
transcribed from csv-spectrum, a conformance suite for CSV parsers. The file
is generated by tools/update-csv-spectrum.R, which records the upstream
commit it was taken from. No csv-spectrum code is included.
