Add Finch to AFproject.org

[boasvdp]

From their website:
"AFproject is a free service for objective performance comparison of alignment-free sequence comparison tools on different datasets."

It is a live benchmarking effort with 12 data sets for benchmarking. Several tools have been added to the benchmark (mash, andi, phylonium etc.), and it might be very interesting to see how Finch compares on different data sets.

Thanks for creating this issue! I hadn't heard of this comparison page before. I'm curious what the results would be too (probably similar to mash since the algorithm is the same modulo filtering); I'll have to put together a submission when I have some free bandwidth.
