Improved saving

Non backwards compatible saving update to save and load from json, this allows for modifying settings in the file and have that reflect during runtime.

But more importantly, if there's missing data it will now fill them in and load properly. This is useful for if new settings are added. Wrong data still causes it to crash though.

v1.1.0

Small fix to filter newlines for PDF files.

Clipboard Narrator v1

With Godot 4 stable being out it's time for the first release of clipboard narrator!

I only added a binary for Windows because on Linux you need to install text-to-speech libraries and there is currently no error when they are missing outside of running the project through the editor. And Mac export gives warnings about Gatekeeper so you may as well just export it yourself I guess?

Documentation for which libraries you need on each distro should eventually be available: godotengine/godot-docs#5823.

It does not seem that they'll be added to Godot itself godotengine/godot#67863 (comment) but there's still an open issue for it here: godotengine/buildroot#7.
