Rewrite with mupdf as a backend (#50)

* Initial implementation of attempted mupdf rewrite

* Change back to no resizing and don't include alpha channel in conversion

* Remove some more dead code

* Make features more modular and call search more easily

* Switch to git dependency for my fixes

* Update deps

* Fix searching hehe

* Remove unnecessary CI steps?

* fontconfig in CI

* perftools in ci

* Final adjustments to conform to mupdf changes
