Title: Documentation fix for `labels` input in random_walker_segmentation.py

This fix was needed because the docstring for `labels` was unclear.
Carrying over from the previous single-channel algorithm, the docstring
claimed `labels` should be "of same shape as `data`", but this is no longer
always the case. When multichannel=True, `labels` should be shaped
like a SINGLE channel of `data`, i.e. without the final dimension denoting
channels.
