[pdal] How do I supply pdal.Filter.icp with the two datasets it needs?

[lefsky at gmail.com]

As per the subject line, I am trying to use pdal.Filter.icp in a script
that uses the python calls, e.g.:

pdal_icp = pdal.Filter.icp(max_iter=100)

However, I don't see in the online references how one specifies an
additional dataset for a single Stage. I have two pipelines- they are the
same except one is for forward scan, the other is for back.

One of those will be passed to  through the pipeline, but how do I tell ICP
to use the results from another pipeline as the other pointcloud.

Partially tested code (Some of it is probably incorrect syntax:

pdal_read = pdal.Reader.las(filename="
https://github.com/PDAL/PDAL/blob/master/test/data/las/1.2-with-color.las?raw=true
").pipeline()

pdal_filtclass = pdal.Filter.range(limits="Classification[2:2]").pipeline()

gdal_outlier=
pdal.Filter.outlier(method="statistical",mean_k=12,multiplier=2)

gdal_splitscan_a =
pdal.Filter.range(limits="ScanDirectionFlag[0:0]").pipeline()
gdal_splitscan_b =
pdal.Filter.range(limits="ScanDirectionFlag[1:1]").pipeline()

pipeline_a = pdal_read | pdal_filtclass | pdal_outlier | pdal_splitscan_a
pipeline_b = pdal_read | pdal_filtclass | pdal_outlier | pdal_splitscan_b

pdal_icp = pdal.Filter.icp(max_iter=100).pipeline(pipeline_a)

But how do I specify pipeline_b?

Thanks for any help you can provide.

P.S. Is there a searchable archive of pdal mailing list posts?
