biology/preseq3.2.0

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.

all: drop support for FreeBSD 13, mips and risc64sf

preseq: Not for 32-bit platforms

Build fails on i386 and bioinformatics generally requires 64 bits

biology/preseq: Predict yield of distinct reads from a genomic library

The preseq package is aimed at predicting the yield of distinct reads
from a genomic library from an initial sequencing experiment. The
estimates can then be used to examine the utility of further
sequencing, optimize the sequencing depth, or to screen multiple
libraries to avoid low complexity samples.
