test_color_brewer_extendability is very very slow

I'm packaging your module as an rpm package so I'm using the typical PEP517 based build, install and test cycle used on building packages from non-root account.

python3 -sBm build -w --no-isolation
because I'm calling build with --no-isolation I'm using during all processes only locally installed modules
install .whl file in </install/prefix> using installer module
run pytest with $PYTHONPATH pointing to sitearch and sitelib inside </install/prefix>
build is performed in env which is cut off from access to the public network (pytest is executed with -m "not network")

Here is pytest output:

```console + PYTHONPATH=/home/tkloczko/rpmbuild/BUILDROOT/python-branca-0.8.0-2.fc37.x86_64/usr/lib64/python3.10/site-packages:/home/tkloczko/rpmbuild/BUILDROOT/python-branca-0.8.0-2.fc37.x86_64/usr/lib/python3.10/site-packages + /usr/bin/pytest -ra -m 'not network' -v ============================= test session starts ============================== platform linux -- Python 3.10.14, pytest-8.2.2, pluggy-1.5.0 -- /usr/bin/python3 cachedir: .pytest_cache rootdir: /home/tkloczko/rpmbuild/BUILD/branca-0.8.0 configfile: setup.cfg collecting ... collected 37 items tests/test_colormap.py::test_simple_step PASSED [ 2%] tests/test_colormap.py::test_simple_linear PASSED [ 5%] tests/test_colormap.py::test_step_color_indexing PASSED [ 8%] tests/test_colormap.py::test_step_color_indexing_larger_index PASSED [ 10%] tests/test_colormap.py::test_linear_color_indexing PASSED [ 13%] tests/test_colormap.py::test_linear_to_step PASSED [ 16%] tests/test_colormap.py::test_step_to_linear PASSED [ 18%] tests/test_colormap.py::test_linear_object PASSED [ 21%] tests/test_colormap.py::test_step_object PASSED [ 24%] tests/test_colormap.py::test_max_labels_linear[10-expected0] PASSED [ 27%] tests/test_colormap.py::test_max_labels_linear[5-expected1] PASSED [ 29%] tests/test_colormap.py::test_max_labels_linear[3-expected2] PASSED [ 32%] tests/test_colormap.py::test_max_labels_step[10-expected0] PASSED [ 35%] tests/test_colormap.py::test_max_labels_step[5-expected1] PASSED [ 37%] tests/test_colormap.py::test_max_labels_step[3-expected2] PASSED [ 40%] tests/test_iframe.py::test_create_empty_iframe PASSED [ 43%] tests/test_iframe.py::test_create_iframe PASSED [ 45%] tests/test_iframe.py::test_rendering_utf8_iframe FAILED [ 48%] tests/test_iframe.py::test_rendering_figure_notebook FAILED [ 51%] tests/test_utilities.py::test_color_brewer_base PASSED [ 54%] tests/test_utilities.py::test_color_brewer_reverse PASSED [ 56%] tests/test_utilities.py::test_color_brewer_extendability ```
