Checking pixellimit for r.import commands

[linakrisztian]

Check the current r.import command against the user cell limit (within ephemeral_processing.py) + added tests for this check

PR additionally contains small linting changes:

• test_download_cache.py (line too long)
• format markdown

May I suggest adding a test test_download_commands_vsicurl similar to

actinia-core/tests/test_geodata_import.py

Line 170 in 852f159

def test_download_commands_tif(self):

The test may then execute two imports:

• r.import on /vsicurl/https://data.mundialis.de/geodata/lulc-germany/classification_2021/classification_map_germany_2021_v01_COG.tif --> should fail as too many pixels
• r.import on /vsicurl/https://github.com/OSGeo/grass/raw/main/raster/r.in.gdal/testsuite/data/elevation.tif --> should succeed as only 150x135 pixels

@neteler Good hint, I will add a test and thanks for the example data.
I had a look and I think it is not reasonable to put it into actinia-core/tests/test_geodata_import.py. Within this test the download and import for vector and raster data is tested.
I will create some separate test-file test_raster_import_pixellimit.py, checking the pixellimit for all r.import commands.

Thanks, well done!

Please rename the tests like suggested or in another way, a negation in the title makes me expect a 400.
Other than that I "only" have ideas for more tests like using the importer, testing the same with ephemeral processing, ... but no blocker for me to be merged like this because tests for two cases exist.

At this point, an importer command would already be translated to r.import, right? So the following would be parsed correctly because it is already transformed?:

 {
            "id": "importer_1",
            "module": "importer",
            "inputs": [
                {
                    "import_descr": {
                        "source": "https://raw.githubusercontent.com/mmacata/pagestest/gh-pages/bonn.geojson",
                        "type": "vector"
                    },
                    "param": "map",
                    "value": "polygon"
                }
            ]
        },

(Maybe add an importer PC to the tests below?) 🙃

Yes it is already transformed at this point. I also added a test for the importer
