v0.3.0

Major highlights:

Creep adjustment

I've implemented it as you have a max margin at the very outside of your signature and the margin gets reduced by the creep adjustment for each layer in. (There's a warning and auto-set button if your max margin doesn't have enough space for all the creep reduction.)

Also, it comes in two flavors: "Per layer" and "From caliper"

Per layer is just your best guess of how much to offset the contents for each sheet of paper in your signature stack. Defaults to 0.1 mm.

From caliper assumes you've taken calipers and measured the thickness of your sheets, and then tries to account for extra creep due to how folds get a bit extra wider each layer in the stack closer to the spine. I'm not sure this is "correct" but it's worth a try if you're trying to be extra specific/exact.

And do let me know if it's not working for you. I haven't used this feature in practice yet, so it's just a best guess so far.

Reworking backend

Did a pretty big rework of how layouts are handled to try to keep the code easier to reason about and expand on.

Fixed MacOS icon size and app bundle

I still need to make a "modern" MacOS app icon so that it looks right under Glass or whatever, but this is at least closer to the right size.

The bigger issue is that I'd screwed up automating the app bundle so all you got was a folder in the .zip file. Now you get a proper .app file like a normal Mac app.
