New fasta_redux (based on Veedrac's fasta)

[llogiq]

I have a gist here It runs roughly 5 times as fast as my previous attempt (on my machine).

I'll obviously submit it to Rust first before putting a PR here.

If you want to build it, you need to add

NUM_CPUS ?= num_cpus-0.2.6

bin/fasta_redux: src/fasta_redux.rs lib/$(NUM_CPUS).pkg

to the Makefile.

I have a rust PR with both fasta and fasta-redux (sans the num_cpus dependency, stubbornly using 4 threads instead).

Now this issue is only waiting on @TeXitoi to submit the new fasta-redux to the benchmarksgame tracker.
