Missing dependency lxml

[shivambl]

I tried this script on an almost fresh Ubuntu 20.04 install but got this error:

Traceback (most recent call last):

    links, failed = zippy.parse_links(urls)

    raise FeatureNotFound(
bs4.FeatureNotFound: Couldn't find a tree builder with the features you requested: lxml. Do you need to install a parser library?

This was fixed by:

pip3 install lxml

I think lxml should be added to the dependencies in the README
