generatevrtwo: Generate virtual GDAL dataset with overviews.

Dataset format:

directory with:
original: symlink to original dataset (anything user provided)
dataset: virtual dataset itself (VRT driver); use this file as an entry point
0-N: directory with overview level

ovr.vrt: virtual dataset encapsulating individual tiles
x-y.tif: file with tile at (x, y)
bg.solid: (optional) dataset with uniform vaulu used in place of missing tiles

NB: symlink to original dataset is used to ease remapping of "vrtwo" dataset when moving around filesystems/machines.
