16bit images and skimage.viewer

[tischi]

The image "04-drawing-bitwise/wellplateImg.tif" is a 16 bit integer RGB image, which skimage.viewer.ImageViewer cannot show out-of-the-box. To see something in the viewer, one for example can divide the image by 65535.0 to convert it to float values between 0.0 and 1.0

The issue is that, I think, this is not explained before students encounter this challenge trying to solve the exercise "Masking a 96-well plate image (50 min)".

Good point @tischi. @tensionhead and I are currently going through the material for the pilot in Heidelberg and stumble on a lot of such issues :/, unfortunately. Highly appreciated that you report this :)
