Check available countries for Qobuz releases

[Deniz8891]

Before I get into my suggestion, let me first appreciate your hard work that resulted in Qobuz support being finally added. Saves a lot of time from doing all the manual look-ups.

With that being said, it might be nice if the regional availability checks are extended onto Qobuz too. Maybe it's already on your to-do list and I don't know if their API returns such info. But I suppose the following bookmarklet which is listed in the other repo hosted by @kellnerd might be helpful:

javascript:(()=>{const e=Array.from(document.querySelectorAll("head > link[rel=alternate]")).map(e=>e.hreflang).map(e=>e.split("-")[1]).filter((e,l,r)=>e&&r.indexOf(e)===l);alert(`Available in ${e.length} countries\n${e.sort().join(", ")}`)})();

This can be especially helpful for those high-res audio releases that are unavailable on Spotify and Deezer.

I had thought about, but the API does not return this information as far as I know. (The API is no longer open for new registrations and the archived documentation is incomplete.)

Unfortunately we would have to scrape the HTML of the www. page, which makes the lookup slower and only works when we know a valid Qobuz region (either from the www. URL or from Harmony's region input).
Because of the additional HTTP request I would like to make available regions an optional property, but then I still haven't implemented any UI or smart logic (if something is already known, skip the extra requests) for these options.
