[GRASS-dev] r.li: new version and tests

No speed test for now; theoretically it should be *much* faster (earlier
rough tests gave a 4x improvements), as it is multithreaded.
The main advantage is that the code is much easier to maintain, and
adding/modifying indices is easier (have you had a look to the code?).
For me it is ready for 6.3; only a few indices are implemented now, but
those who are should be ok. I would vote for having it included in trunk.
