consider renaming this module

[tiagofilipe12]

While exploring bionode modules I found two modules which name suggested the same functionality. Currently bionode has bionode-fasta and this repository (fasta-parser). While bionode-fasta parses a fasta file to a streamable object, this module (fasta-parser) parses fasta to json only. Therefore I think a more accurate naming would be something like fasta2json.
