Add some raster files for testing the to-be-added raster functions in
SedonaDB (#10)
Some of the test files were taken from the apache/sedona repository (see
https://github.com/apache/sedona/tree/master/spark/common/src/test/resources/raster);
some other files were cropped tiles of famous raster dataset, including NAIP,
Landsat-8, Sentinel-2 and AlphaEarth.

+# Raster Test Files
+
+This directory contains raster files used for testing Sedona's raster
functionality.
+Files are sourced from public datasets and the [Apache Sedona test
resources](https://github.com/apache/sedona/tree/master/spark/common/src/test/resources/raster).
+
