v1.2.1

What's Changed

• Steam updated their licenses page to be paginated so we can no-longer fetch in a single request. This unfortunately slows the cache-fetching speed (from a single sub-second request to N/100 requests where N is game licenses), but using an incremental cache merge strategy means it's not all or nothing.
• Style hover tooltip like the nearby native steam elements by @BlythT in #14
• Phase 1 internal refactor by @BlythT in #15
