Fix document reloading with delete-then-write editors and redo BottomMessage updating to work better

* Relicense to GPLv3 since poppler is GPL and we must not violate that license

* Add note to README that contributions will be licensed as MPL-2.0

 - Move `ratatui-image/vb64` support under `nightly` feature, enabled by default
 - Fixed a bug where jumping to a page out of range could result in weird `esc` key behavior
 - Added CI ([#31](https://github.com/itsjunetime/tdf/pull/31), thank you [@Kriejstal](https://github.com/Kreijstal))
+- Changed global allocator to [`mimalloc`](https://github.com/purpleprotocol/mimalloc_rust) for slightly improved performance
+- Fixed issue with document reloading not working when files are intermedially deleted
+- Fixed a lot of weirdness with bottom message layering/updating
