PL

To address #15.

 -b, --blobs        -- Directory for Blobs. By default, it will create

                       path is provided -b path/to/blobs

• argparse is used to handle argv.
• -b, --blobs is optional.

@FarooqAlaulddin Could you please run the tests locally using tox -pauto?
There are some linting tests which fail and the code does not run on Python < 3.9.
(Sorry GitHub Actions was disabled, so the failures do not yet show up here. But for your next commit they will run again.)

Once the comment is removed this looks good, thank you.
