Upgrade scikit-image to >=0.19.3 in requirements.txt

[Nelson-Gon]

Hi,

The current version of scikit-image listed in the requirements file has a bug in phase_cross_correlation. This can lead to unexpected results in the alignment of SBS cycle images.

Specifically, in my experience the values after registration are not always in the expected range although the alignment would appear fine.

Please see scikit-image/scikit-image#5461 and the issues linked to the same pull request.

However, also note scikit-image/scikit-image#6456

Thank you,
NelsonGon
