WIP: add script to test changes to trending pages

[javierggt]

Description

This PR adds a script to quickly test changes to the web scraper.

The following produces an html page with the output of one single scraped page, fetching it from the default URL:

twiki_test acq_stat_reports

Typically, when makes changes to the scraper, there will be a test page somewhere to scrape from. For example:

twiki_test kalman_watch3 --url https://icxc.cfa.harvard.edu/aspect/test_review_outputs/kalman_watch/pr-16/no-rad-data

produces a test page with scraped data from the given URL.

👍 Great idea.

@jeanconn I fixed a hiccup (it was not working with classes that re-implemented get_url, but I hope it's ok now.

[javierggt]

it will still not work in all cases... we can wait until I am testing acq_stats

[jeanconn]

Maybe mark this PR as a draft for now? I think #34 can just get merged and a release installed.
