[pdal] PDAL Python bindings

[Stefan Ziegler]

Use case 1: We have approx. 1000 tiles (one sqkm each) and need to
reproject them. Afterwards we nee to adjust the bounding boxes to "nice"
coordinates again. Let's say the source bbox is something like
620'000/240'000, 621'000/241'000. After reprojecting it will be
2'620'000.55/1'240'000.34, 2'621'000.58/1'241'000.37. But we want a bbox
like this: 2'620'000/1'240'000, 2'621'000/1'241'000. I can achieve this
with available pdal features (tindex, translate etc.) and some python
script for the loop with system calls (for pdal).

Use case 2: Some small (wsgi) webservice like requesting lidar data with a
bounding/polygon as parameter value. Again I could do this wie os.system().

Any hints are welcomed if I do not see the wood for the trees :)

regards
Stefan
