Title: Major update to focal operations.

This commit does some renaming (Focus -> Kernel, Context -> Strategy), adds
some new focal operations like Moran's I and Hillshade, and contains some other
fixes.

Focal operations still need a bit of profiling and optimization love, as well
as better parallelization support.
