[pdal] filters.stats output

[Andrew Bell]

I should have added the output:

$ bin/pdal info --stats myfile.las
--filters.stats.dimensions=Classification
--filters.stats.count=Classification
{
  "filename": "..\/test\/data\/las\/autzen_trim.las",
  "pdal_version": "1.3.0 (git-version: 3ca196)",
  "stats":
  {
    "statistic":
    [
      {
        "average": 1.237336364,
        "count": 110000,
        "counts":
        [
          "1.000000\/83893",
          "2.000000\/26107"
        ],
        "kurtosis": -4.857351452e+15,
        "maximum": 2,
        "minimum": 1,
        "name": "Classification",
        "position": 0,
        "skewness": 2.177023909e+15,
        "stddev": 0.4254905513,
        "variance": 0.1810422092
      }
    ]
  }
}
