Update Madewithlau

[mlduff]

Looks like madewithlau.com underwent some changes in their website. The new website uses a tRPC API to load data after the initial page load. There is some fairly complex cross-referencing of returned data, hence the complexity of this PR.

I also added a utility to get the URL slug.

Resolves #1015

This generally looks great to me, thank you @mlduff. Only one change required:

Either:

• Add some test coverage for _get_url_slug
  or
• Relocate _get_url_slug to the madewithlau.py scraper module (removing the re-use from goustojson.py)

@jayaddison Test should be added - let me know if you want more tests

[jayaddison]

Thanks @mlduff - no need for the additional test coverage at the moment; it's mainly intended to help by providing a known place where we can add test coverage if the expectations of different scrapers diverge.

@mlduff this has been included and released in v14.56.0 (and also the pre-release v15.0.0-rc3) of recipe-scrapers on PyPi.

[jayaddison]

Ah, a correction, sorry - this is included in v14.56.0 but not included in v15.0.0-rc3 (since the v15 branch does not currently include scrapers that require more than the initial HTTP network request to retrieve HTML).
