feat: add Zillow module - #396

@shredzwho We don't need a separate test file for each module, so you can remove it.

One thing we've recently introduced is the extra parameter in Result.taken() to pass any additional data that a site exposes about a user. If this site returns profile metadata publicly, try extracting those details with regex (or another appropriate parser) and pass them through extra.

If the profile data is only available after login or signup, let me know and I will merge it as it is for now.

Hey @shredzwho! 👋

Just checking in on this PR. It's been open for a while and I noticed it has the help wanted label.

I'd be happy to help finish it up by:

• Removing the test file (as requested)
• Adding extra data extraction for any public profile metadata

Are you still working on this? If not, I can pick it up and open a new PR with the changes.

Let me know! 🙌
