Conda release of v0.13.2

@avaldebe conda-forge/pyaerocom-feedstock#21 PR is failing to build.
A similar PR created by a bot conda-forge/pyaerocom-feedstock#22 also fails to build.

From the pipeline logs it seems that conda_build does not understand PEP 517 and needs flit_core to be installed into the build environment.

ModuleNotFoundError: No module named 'flit_core'

The tests now are failing after DeprecationWarning triggered by importlib.resources on Python 3.11.

tests/io/test_read_eea_aqerep_v2.py::test_read
  $PREFIX/lib/python3.11/site-packages/pyaerocom/io/helpers.py:301: DeprecationWarning: path is deprecated. Use files() instead. Refer to https://importlib-resources.readthedocs.io/en/latest/using.html#migrating-from-legacy for migration advice.
    with resources.path("pyaerocom.data", COUNTRY_CODE_FILE) as path:

see pipeline logs for more details

I will silence the warnings on conda-forge tests and further investigate the Python 3.11 DeprecationWarning on PR #783.

[avaldebe]

the error now is

    def test_EbasNasaAmesFile_head_fix_error(filedata):
        with pytest.raises(AttributeError) as e:
            filedata.head_fix = "Blaaaaaaaaaaaaaaa"

Looks like the problem is related to running under Python 3.11, which we do not fully support.

    python:               3.11.0-ha86cf86_0_cpython     conda-forge

What would you say about excluding Python 3.11 from this particular release?

[lewisblake]

To me that's fair. Thoughts @dulte @jgriesfeller ?

[jgriesfeller]

Agreed. Let's exclude Python 3.11 for now.

[avaldebe]

conda-forge/pyaerocom-feedstock#21 is passing now (for python >=3.8,<3.11), it is now up to @dulte to approve that PR

[lewisblake]

Next meeting suggestions: #519 and updating some of the labels for issues (i.e., consider having project-specific labels)
