Convert Supernova assembler "raw" style FASTA output (see https://support.10xgenomics.com/de-novo-assembly/software/pipelines/latest/output/generating) to GFA format
Usage:
python 10X_fasta_to_gfa.py example_raw_fasta.fasta
(outputs GFA on stdout)
It ain't fast, and will probably break in the future, but it gets the job done.
