interact function arg names and range

Hello,

Thank you for the great tools! I ran into an issue with the interact function; I figured it out, but I thought I would make a note here in case someone else runs into the same issue.

When using a custom function if you choose certain args, you will get pre-defined ranges according to:

def guess_range(name, annotation):
if name == 'footprint' or name == 'selem' or name == 'structuring_element':
return 0, 100, 1
if 'sigma' in name:
return 0, 25, 1
if 'radius' in name:
return 0, 100, 1
if 'factor' in name:
return 0, 100, 1
if name == 'angle' or "degrees" in name:
return 0, 360, 15
return None, None, None
