Two tiles fail due to KeyError in `skimage.measure.find_contours`

[robbibt]

Contour extraction on two Albers tiles are currently failing with a KeyError. This has been raised on the scikit-image Github here:
scikit-image/scikit-image#4505

These two tiles may not be able to be processed until this bug has been resolved and the new version of scikit-image made available on the NCI.
