write_parquet() writes a list of raw vectors as a binary (BYTE_ARRAY)
column, with NULL for a missing value, and parquet_schema() declares it
as "BINARY", "GEOMETRY" or "GEOGRAPHY". The geospatial types hold
well-known binary with a crs (and, for GEOGRAPHY, an edge algorithm),
and qio records each column chunk's geospatial statistics.geospatial_statistics() reports the bounding box and geometry types of
every GEOMETRY and GEOGRAPHY column chunk, so readers can choose row
groups by box before reading data.- Fixed the vendored carquet writer recording, for every row group after the
first, geospatial statistics that included the earlier row groups.
schema() reports a GEOMETRY or GEOGRAPHY CRS whole however long it is.
Files that put inline PROJJSON there, as DuckDB does, had it cut to 127
bytes.

- Fixed undefined behavior reported by CRAN's sanitizer checks (M1-SAN,
clang-UBSAN and gcc-UBSAN). Batch reads no longer load integer and
floating-point values through misaligned pointers, and writing a string
column that contains empty strings no longer passes a NULL pointer to
memcmp() or memcpy(). Results were already correct; only the undefined
behavior is removed.
