Improved image carving

JGCGen now has better support for image carving. Since the previous post, I've added two major features. The first is a roughing strategy for removing lots of material fast and in multiple passes so you can carve deeper. The second is the decoupling of image resolution from carving resolution. Stepover distance can now be smaller than a single pixel and jgcgen will interpolate the values in between. Another important change was a rather embarrassing bug fix: the tool shape profiles for flat and ballnose endmills were swapped! No wonder the previous test looked flatter than I expected...

Still on the TODO list: optimize rough path generation to minimize rapids and implement a waterline strategy.
