feat: wip hltb scraper service

[kswilliames]

Replaces the deprecated HowLongToBeat API website with an API client that supports search via the HowLongToBeat Search API and/or scraping the HowLongToBeat HTML game page. HLTB API is inspired by howlongtobeat npm package.

Completed

• Completed a search/detail API for fetching HLTB data
• Unit testing for search and detail HLTB API

Todo

• Replace existing API calls to howlongtobeatsteam.com with search/scrape as appropriate (search API preferred)
• Replace UI dialog integrations to support bulk scraping similar to existing Steam scraping integration
• Improve efficiency of API calls to reduce potential for negative impact on howlongtobeat.com and potential blocking by CSRF tokenisatio. Implement via caching/API call optimisation.
