* Renamed `guidata.userconfigio` to `guidata.dataset.iniio`
* New package `guidata.utils` for utility functions:
* Removed deprecated or unused functions in old `guidata.utils` module
* Moved old `guidata.utils` module to `guidata.utils.misc`, except the
functions `update_dataset` and `restore_dataset` which are still in
`guidata.utils` (root module)

to show test module in test launcher (this replaces the old `SHOW = True` line)

dataset creation, allowing to create a dataset with a single line of code by
passing default item values as keyword arguments

Older releases

Bug fixes:

* Fixed critical compatibility issue with Python 3.11 (`codeset` argument was removed
from `gettext.translation` function)
* Fixed support for `DateTimeItem` and `DateItem` objects serializing (HDF5 and JSON)
* Fixed JSONReader constructor documentation: more explicit docstring
* Fixed test_dataframeeditor.py test script (issue with QApplication creation)

Changes:

* Added JSON serialize/deserialize support for `DataSet` objects (from CodraFT project,
<https://codra-ingenierie-informatique.github.io/CodraFT/>)

* Object editor (`oedit` function): cleaner implementation, handling widget
parenting (code specifically related to Spyder internal shell was removed)

it already has been initialized (QApplication instance is not None)
