If the caller constructs a SlicerSourceMesh and passes it to the Slice overload that accepts it, the algorithm can avoid a lot of allocations from fetching mesh data. The caller can also opt to not produce either the upper or lower hull if they don't need it. With my 60-triangle test mesh, this takes allocations from 80-100 KB to 17-22 KB, and execution time from the high 2 ms to the low-mid 2 ms. The public API is fully backwards-compatible.

This contains some changes to enable callers to significantly reduce allocations if they are slicing the same mesh multiple times:
