Load stopwords from a file

Supplying a long list of stopwords as an inline CLI argument can be tricky or even impossible. having an option to load it from a file would be great.

It looks like the default list of stopwords is hard-coded in a Python file. Perhaps it will be more flexible to extract it out as a text file and iterate over it during the loading process. This way, a custom list of stopwords can be provided the same way as the default one.
