filter islands equivalent for lines #373

My usecase: I make a decorative graphic based on road data.

I know that road network is continuous, but there are small lines that are unconnected to the main network.

I want to

(a) remove them (to keep from main result) (b) keep only small areas (to produce debug build to easily check how significant is problem - maybe data should be slightly improved to connect them)

below: diagnostic rendering with multiple broken segments

In this case I would be happy to try implementing this - if such improvement has chance to be accepted and it is likely that such change is doable for someone new to the codebase.

This is not a good "first issue" for someone not familiar with the codebase.

It seems like a worthwhile addition... I'll think about the best way to add this functionality.
