[pdal] clustering without ground returns

[Bradley Chambers]

There is not a way to do this out of the box, though we've discussed the
need from time to time [1].

You can probably get away with using tags and inputs as described in the
pipeline documentation and tests [2, 3]. This effectively creates two
pipelines under the hood though.

Would it help if the cluster filter simply added an ignore option similar
to SMRF [4]?
