new imageio version breaks over numpy versions.

[morcoGreen]

imageio introduced new version which requires numpy > 1.20 over its ArrayLike object.

imgaug doesn't seem to set specfic version of imageio, therefore takes the latest version : https://github.com/aleju/imgaug/blob/master/requirements.txt#L12

The result: imgaug installation breaks code over incompatible numpy version:

    import imgaug
  File "/usr/local/lib/python3.6/site-packages/imgaug/__init__.py", line 7, in <module>
    from imgaug.imgaug import *  # pylint: disable=redefined-builtin

    import imageio

    from numpy.typing import ArrayLike
