Release v1.1

Hello everyone,

I'm happy to release the first version of my PaletteBuilder tool.  I built it to help me generate palette ramps for my pixel-art game projects, but hopefully you will find it useful too!

I developed it in Godot 4, partly as a learning exercise with UI elements.  The final executable is a bit large for what it is (138MB unzipped, 57MB zipped) because it still has to include the whole Godot engine.  So unfortunately there's not much I can do to reduce the file size without rebuilding the project on another platform.

I'm still working on a release for MacOS, so please bare with me.

If you find any bugs or have suggestions on small tweaks that could make the UI easier to work with, please drop me a comment!
