[pdal] PdalXML style

[Michael P. Gerlek]

So now I'm leaning towards this:

<Writer type="drivers.las.writer">
        <Options>
                <option>
                        <name>filename</name>
                        <value>out.laz</value>
                </option>
                <compression>true</compression>
                <option>
                        <name>filename</name>
                        <value>out.laz</value>
                </option>
        </Options>
        ...

While thuddingly verbose, it allows the Options block to be read as a native
property tree (something Howard wanted/expected, but which I didn't fully
grok until now).

The syntax might evolve further if I can turn the pipeline stages into
property tree notation as well.
