added gdal docker build

docker-helper-images/gdal-docker/README.md

+The version downloaded apparently doesn't yield the correct version when using releases, therefore 
+a change in `gdal/docker/ubuntu-full/bh-gdal.sh` might be needed:
+
+
+```bash
+# ...
+
+# comment out
+# wget -q "https://github.com/${GDAL_REPOSITORY}/archive/${GDAL_VERSION}.tar.gz" \
+#     -O - | tar xz -C gdal --strip-components=1
+
+# removes the "v"
+GDAL_V=${GDAL_VERSION#?}
+wget -q "https://github.com/${GDAL_REPOSITORY}/releases/download/v${GDAL_V}/gdal-${GDAL_V}.tar.gz" \
+    -O - | tar xz -C gdal --strip-components=1
+
+# ...
+```
+
+**and replace** in `ubunutu-full/Dockerfile`:
+
+```dockerfile
+ARG WITH_FILEGDB=
+```
+
+with
+
+```dockerfile
+ARG WITH_FILEGDB=1
+```
+
+
+**if issues with libjxl, checkout specific version**:
+
+ie. -> `&& git checkout v0.6.1`
+
+```dockerfile
+# Build libjxl
+RUN . /buildscripts/bh-set-envvars.sh \
+    && git clone https://github.com/libjxl/libjxl.git \
+    && cd libjxl \
+    && git checkout v0.6.1 \
+    && git submodule update --init --recursive \
+    && mkdir build \
+    && cd build \
+    && cmake -DCMAKE_INSTALL_PREFIX=/usr -DCMAKE_BUILD_TYPE=Release -DBUILD_TESTING=OFF .. \
+    && make -j$(nproc) \
+    && make -j$(nproc) install \
+    && make install DESTDIR="/build_thirdparty" \
+    && cd ../.. \
+    && rm -rf libjxl
+```
