Title: Removed requirement for contiguous bounds in area_weights()

Currently ```iris.analysis.cartography.area_weights()``` raises an exception if the lat lon coords do not have contiguous bounds. I believe this to be overly restrictive and unnecessary. This PR reduces this condition to only requiring the coordinates to have bounds.
