Warning about using JpegImageFile under Python 3.11 #55

Description

@poke1024

When running this under Python 3.11.3 as ipyplot.plot_images(images) where images is an array of PIL.Image (actually JpegImageFile), I get the following warning:

.../lib/python3.11/site-packages/ipyplot/_utils.py:95: FutureWarning: The input object of type 'JpegImageFile' is an array-like implementing one of the corresponding protocols (`__array__`, `__array_interface__` or `__array_struct__`); but not a sequence (or 0-D). In the future, this object will be coerced as if it was first converted using `np.array(obj)`. To retain the old behaviour, you have to either modify the type 'JpegImageFile', or assign to an empty array created with `np.empty(correct_shape, dtype=object)`.
  return np.asarray(seq, dtype=type(seq[0]))

Is this already known?
