New optional `remove_published` option

Version 2.1 introduces a remove_published option for removing the last updated timestamp from Atom feeds so that subsequent scrapes will pass a diff check (thus preventing unnecessary commits if the feed is unchanged). The documentation has also been updated.

Version 2, now using `@extractus/feed-extractor` tool

This release uses @extractus/feed-extractor for greater versatility and more powerful standardization, while preserving the ability to save feeds in an unopinionated way if you so choose.
