New #Nostur update

What started as small bug fixes now become a bit of a big overhaul of how Nostur loads and renders things. I spent the last few days changing many things under the hood. Everything should feel faster now, especially when the caches are loaded. If you are trying Nostur for the first time, give it a moment to warm up the caches, after that everything should be fast.

Other changes:

- Profile media: load most recent media first

- Add ‘show more’ for posts too long

- Added support for kind 1063 images

- Fixed lnurl decoding
