grass.jupyter: add SeriesMap and tests

[chaedri]

SeriesMap creates a ipywidgets Slider for scrolling between a list of rasters and/or vectors.

series = gj.SeriesMap(height = 500)
series.add_rasters(["elevation_shade", "geology", "soils"])
series.add_vectors(["streams", "streets", "viewpoints"], color="blue")
series.d_barscale()
series.show()

A re-write of #2996 that is better: shorter code, a fewer bugs/ways to break it.

This looks good! Just the test and flake8 are failing and I added couple comments.

@wenzeslaus I'm having trouble getting the pylint disable=duplicate-code to work with the checks in GitHub. The way I have it setup now effectively removes the error on my local machine but it's still failing during the GitHub checks.

[petrasovaa]

I think this is ready to be merged.

[wenzeslaus]

Please create an issue for the duplicate code. One issue just for the specific code issue is enough. The Pylint config is part of a bigger issue of reducing Pylint warnings.

The only check that isn't passing is pytest. It passes on my local ubuntu machine but fails in GitHub actions with the error:

FAILED python/grass/jupyter/tests/seriesmap_test.py::test_default_init - NameError: Could not find a raster named precipitation_1
FAILED python/grass/jupyter/tests/seriesmap_test.py::test_render_layers - NameError: Could not find a raster named precipitation_3
FAILED python/grass/jupyter/tests/seriesmap_test.py::test_save - NameError: Could not find a raster named precipitation_1
================== 3 failed, 100 passed in 215.91s (0:03:35) ===================

I'm not sure why it would find these rasters on my machine but not in the checks because the rasters are created as a pytest Fixture in conftest.py by space_time_raster_dataset. Any ideas?

There is the same error for vectors...

[petrasovaa]

There is still the bug in add_vectors and see Vashek's comment to create an issue about the code duplication.

Already adressed
