fix(python/sedonadb): skip RS_ReprojectMatch null-raster test without rasterio

[jiayuasu]

test_reproject_match_null_raster_is_null calls write_grid_geotiff, which imports rasterio, but is missing the pytest.importorskip("rasterio") guard that the other rasterio-dependent tests in the same file already have (see test_reproject_match_int64_uint64_rejected and test_reproject_match_sql_smoke). It therefore fails with ModuleNotFoundError in any environment without rasterio, rather than skipping like its neighbours.

This is currently breaking the wheel builds. CIBW_TEST_REQUIRES installs pytest adbc_driver_manager geoarrow-pyarrow geopandas duckdb — no rasterio — so python-wheels runs fail on this one test:

tests/functions/test_rs_reprojectmatch.py::test_reproject_match_null_raster_is_null FAILED
================ 1 failed, 3143 passed, 2495 skipped in 25.01s =================

>       import rasterio
E       ModuleNotFoundError: No module named 'rasterio'

Every python-wheels run on main has failed this way for several days, across linux-arm64, linux-x86_64, macOS-arm64, macOS-amd64, and windows-x86_64, which also skips the expr, zarr, and nightly-upload jobs.

Change

One line, matching the convention used elsewhere in this file and in the other test_rs_*.py modules:

pytest.importorskip("rasterio")  # write_grid_geotiff needs rasterio

Verification

Reproduced locally in an environment without rasterio: the test failed before the change, and afterwards the module reports 13 skipped, 0 failed. ruff format and ruff check are clean.

Note

The alternative would be adding rasterio to CIBW_TEST_REQUIRES so these tests actually run during wheel builds. Worth considering separately: 12 of the 13 tests in this module already skip in that environment, so raster coverage there is currently minimal. That is a coverage decision rather than a fix for the broken build, so this PR only restores the skip behaviour the module already intends.
