biology/megahit1.2.9.22

Release numerous ports to ports@

I've been retired for a few years, and it is unlikely I will be doing
any more scientific computing support in the future.  I have continued
to maintain ~160 ports to the best of my ability, mainly as a favor to
the community, but I can no longer justify the time and effort
required.  I am therefore releasing most of my scientific ports, along
with a few others, to ports@.  I will continue to maintain ports I am
actively using and those for which I am upstream.

biology/megahit: Ultra-fast single-node metagenomics assembly

MEGAHIT is a single node assembler for large and complex metagenomics
NGS reads, such as soil. It makes use of succinct de Bruijn graph
(SdBG) to achieve low memory assembly. MEGAHIT can optionally utilize
a CUDA-enabled GPU to accelerate its SdBG contstruction.
