new workflow

[bowmanjeffs]

Alter workflow so that all files are analyzed as singular together. This should improve run time and clean up a few lingering issues. First step is to parse all fasta files and create an asv abundance table (useful anyway). The asv becomes the master index to which everyone else is linked. For example, an ASV only needs to classified and metabolic inference completed once. This information can then be mapped back into the abundance table.
