------------------
- Add --oo (open) options and --wo (warp) options like those of gdalwarp. These
allow control over, for example, overview level of TMS datasets and the
number of threads used internally by GDAL's warper.
- Add a --cutline option that takes an optional path to a GeoJSON
FeatureCollection (62). No pixels outside the cutline shape(s) will be
exported and no tiles outside the cutline will be generated.
