[pdal] filtering pipeline result

[Giuseppe Falcone]

Hi to all,

I have a pipe that elaborate a las file. on the pipe.arrays[0] command I
have, as result, a ndarray.
I want to split this array in twa subarray: the first with element that
have ReturnNumber dimension = 1 and the second with all others elements.

There is an efficient way to do this?
Thanks.

Giuseppe
