- fix: fix accessing inherited non-scalar temporary or plugin features
for RTDC_Hierarchy class (165)
- fix: properly handle user-defined (temporary or plugin) features
when exporting to HDF5 (166)
- enh: add "shape" keyword argument in RTDCWrite.store_feature to
allow the user to pass the correct data shape; this reduces warning
messages when using the RTDCBase.export.hdf5 functionality
- ref: simplify data export to HDF5 with generator function
- tests: use correct tdms-dataset for tdms tests

- fix: enable loading of non-scalar plugin data as h5py.Dataset (162)
- build: minor fixes in CI and testing pipeline

- fix: recompute the "ml_class" feature if the ml_score features
change (either the underlying model or the number of features)

- fix: support nan values for the computation of the "ml_class"
feature (161)
- fix: cache of util.hashfile used access times of files (and thus
might not have been of any use in some cases)

- fix: misleading error message when loading plugin features
with Python modules that are not available (160)
- docs: add information on how to call CLI functions from within
Python (145)

- fix: make absolutely sure HDF5 files are closed if RTDCWriter is
used as a context manager
- docs: properly document the shapes option of plugin features (146)
