Updated pdal matrix transform pipeline, updated PDAL version

[pierotofy]

Fixes #522. Upgrades PDAL to include the changes to use double precision in the PLY reader.

This will also see improvements in the DEM progressive morphological filter.

I got this error:

Here's my json file:

{
    "pipeline":[
        "input.las",
    {
        "type":"filters.sample",
        "radius":"1.0"
    },
    {
        "type":"filters.pmf",
        "extract":"true"
    },
    {
        "resolution": 2,
        "radius": 0.5,
        "output_type":"idw",
        "filename":"outputfile.tif"
    }
    ]
}

[dakotabenjamin]

Simply removing the "extract":"true" line fixed it

Now it doesn't extract... Need to add:

{
  "type":"filters.range",
  "limits":"Classification[2:2]"
}

Here's a patch:
