Adds support for DSP SIFT #1712

Closes #1710, although leaves min-num-features in place for the time being.

This descriptor/detector looks very promising, although it's slower by a factor of ~2x.

For comparison, this is the sparse point cloud graph / match graph for Brighton Beach processed with --feature-type dspsift:

I also still need to port and test the affine shape estimation, I'm not sure if that will bring additional improvements.

So far it seems to be able to handle forest areas / poor overlap datasets with much better results. Would love for people to help test before I complete the rest and merge it.
