[Feature] QR code quite zone

[rylydou]

Amazing work on this extension! I've been trying to find a qr code plugin that actually works for a while now. Before this I tried using a modified version of this addon for the a little bit but it was super buggy.

This PR adds padding support for the qr code texture. The padding is based on module_px_size. The color uses the light_module_color.

Here's what a padding size of 1 looks like:

I can't figure out how to get the inspector to only allow positive numbers and zero. I tried editor_hint: '0,1,or_greater' but it doesn't seam to work.

Oops turns out my commits aren't signed I need to fix that.

Thank you for the suggestion!
The correct term you are looking for is quiet_zone, by default it should be 4 (Chapter 6.3.8)

If you are are ready, that i can review this PR, just ping me.

If possible could you remove the spaces inside the brackets in the commit message? thanks.

I renamed the properties and I figured out how to block negative values from being entered. The default is still 1 but there is a tool tip explaining that 4 is recommend by the standard. (Feel free to change it to 4 if you want)

I'm not sure if I can rename the older commits but when you merge this PR you I think it will get squashed. (I'm still a git noob apparently)

Yes sure, just edit them, or make your changes, squash yourself, rename the squashed commit and force push to your branch.
