Appearance: Option Image border radius

[OleksGubanov]

I encountered a problem with adding an image to a creature sheet. The image became rounded. I didn't like it: it hid part of my image and looked bad.
So I started digging through the plugin and looking for settings. (Yes, that was the first day I installed the plugin, today is the second.)
I couldn't find a setting that allowed me to adjust the image border radius in the style, so I decided to change it myself.
I added a new parameter: image-border-radius. I added a menu for it, all done in the plugin's main file.
Then, at the end of the CSS file, I added the usage of this parameter.
I'm not very knowledgeable about this, and the files I'll attach may contain other changes I made while trying to achieve the desired result. But I think you guys who created this plugin can do it competently.

The task is to add an option in the layout style settings for changing the border radius.
