More improvements to Sobol sampling.
...
- Added an additional scramble round to the Owen scrambling, with
new optimized constants.
- Reordered the dimensions of the direction numbers to improve 2d
projections between adjecent dimensions. Only did this for
dimensions under ~40.

Also switching to one of the alternates, as it seems to give
better results than the one I was using before.

Generate sobol direction numbers from text file.

This way the numbers aren't cluttering up the source file, and
this also makes it easier to play with other direction numbers.
