`quickinfo` is missing values

[normanb]

Comparing

pdal info --summary autzen.laz | jq .

against

import pdal
r = pdal.Reader(filename="autzen.laz")
p = r.pipeline()
p.quickinfo

The python output is missing metadata, e.g. offsets and scales.

The difference is due to the info kernel here

https://github.com/PDAL/PDAL/blob/master/kernels/InfoKernel.cpp#L182

and calling inspect here

https://github.com/PDAL/PDAL/blob/master/io/LasReader.cpp#L254

I will be working on this shortly and will get a PR up for review.
