New Brands

Based on some feedback we've been receiving via email and social I'm adding several new brands, including: Amazon, Apple App Store, Google Play Store, and OnlyFans. Added a SVG of the LittleLink avatar. Cleaned up the README.md to make it more readable, updated some outdated content, and added a new Analytics section promoting Fathom (and adding a referral link to help support LittleLink). I also posted a link to the public LittleLink Fathom analytics dashboard.
