src/Tweeper.php: fix rendering Instagram images in some feed readers

Instagram.com is using Cross Origin Resource Policy and this prevents
images in RSS items from being displayed in the Web view of some feed
readers like Liferea.

Add a function to generate Data URLs with base64 payloads and use that
for instagram images a s a workaround to fix rendering images in some
feed readers.
