Seqret

What's Changed
This update adds CLI functionality to SeqRET, while maintaining the existing web app.

Users can now input a single sequence in the CLI using `seqret optimize -s [SEQUENCE]`, or specify a CSV file with `seqret optimize -i [INPUT CSV] -o [OUTPUT CSV]`.

The web app can be launched with `seqret webapp`.
