[pdal] Greedy Projection FIlter

[Paul Harwood]

Thanks Andrew,

I have never tried it before so I cannot claim to be a regular user.

I also cannot do any debugging - I don't have a PDAL dev environment and
cannot afford the time to crate one at the moment.

I will consider it "Not working" for the time being and create a bug.
