Title: `pdal attribute`

It would be handy to have a kernel application that did the following:

* Define an OGR query to fetch polygons along with a column for values
* Select all the points inside each polygon in the OGR selection
* Set the attribute for the specified dimension to the result of the query

```

pdal-compressed.laz

SELECT GEOMETRY, ID FROM polygons

Classification

../las/1.2-with-color.las

```
