Should Quickinfo output the same metadata key-values that a `pdal info --summary` call would?

[kylemann16]

A quickinfo call returns a set group of key-value pairs, when PDAL's metadata collection and output are not so defined. Should the output from pdal info --summary on the command line be the same as a pipeline.quickinfo in python?

For example, I need the STAC Ids from an ItemCollection that matches the params I have.

A call to pdal info --summary --driver readers.stac on the command line might look like this:

$pdal info --summary --driver readers.stac --debug --readers.stac.asset_names 'ept.json' --readers.stac.item_ids '^(USGS_LPC_){0,1}MI_\w{0,}' https://s3-us-west-2.amazonaws.com/usgs-lidar-stac/ept/item_collection.json

      "minx": -10066325,
      "miny": 5113087,
      "minz": -4503
    },
    "dimensions": "Classification, EdgeOfFlightLine, GpsTime, Intensity, KeyPoint, NumberOfReturns, Overlap, PointSourceId, ReturnNumber, ScanAngleRank, ScanChannel, ScanDirectionFlag, Synthetic, UserData, Withheld, X, Y, Z, OriginId, Pulse width, Blue, Green, Red",
    "metadata":
    {
      "ids":
      [
        "MI_31Co_Barry_2016",
        "MI_31Co_ChippewaCo_TL_2017",
        ...
      ],
      "item_ids":
      [
        "MI_31Co_Barry_2016",
        "MI_31Co_ChippewaCo_TL_2017",
        ...
      ]
    },
    "num_points": 768598386500
  }
}

If I do the equivalent call in pdal-python with this call and output:

>>> reader = pdal.Reader.stac(filename='https://s3-us-west-2.amazonaws.com/usgs-lidar-stac/ept/item_collection.json', item_ids=['^(USGS_LPC_){0,1}MI_\\w{0,}'], asset_names=['ept.json'])
>>> p = reader.pipeline()
>>> qi = p.quickinfo
>>> qi['readers.stac']

    qi = p.quickinfo
         ^^^^^^^^^^^
RuntimeError: readers.ept: Could not read from 's3-us-west-2.amazonaws.com/usgs-lidar-public/USGS_LPC_MI_ManisteeCo_2015_LAS_2017/ept.json'.

Your example fails for me.
