Intermittent pytest raster subsetting failures

[jpswinski]

Intermittently, the raster subsetting test will fail with one of the asserted values being close but not exact. It is unclear why there is non-determinism in the test execution.

    def test_rasterize(self, init):
        resource = "ATL03_20181017222812_02950102_005_01.h5"
        region = sliderule.toregion(os.path.join(TESTDIR, "data/grandmesa.geojson"))
        parms = {
            "poly": region['poly'],
            "raster": region['raster'],
            "srt": icesat2.SRT_LAND,

            "res": 20.0 }
        gdf = icesat2.atl06p(parms, resources=[resource])
        assert init

See above commit - pytest conditions are relaxed to allow tests to pass (and catch other issues). Once this issue is resolved, the test needs to be updated again to put back the stricter condition.
