Copper buckle repair function

* FIX currently supports manual copper buckle repair function

* Requires a separate installation package

* Supported from FIX version 2827 onwards

Usage scenarios and methods:

1. After automatic material counting, it was found that the copper buckle in the image affected the calculation

2. Click "Draw Copper" to enter the drawing state. There is a yellow circle on the mouse, which represents the brush size. Use Ctrl+scroll wheel to adjust the brush size.

3. Draw a yellow line to cover the entire copper buckle

4. Click "Draw Copper" or the spacebar to close the canvas and repair the copper button.

Repeatedly click "Draw Copper" or the space bar to switch between the canvas and repair states, making it easier to confirm the repair results.

5. You can also click Auto directly to order materials.

Other notes:

• FIX will save the drawn canvas filename-inp.png in the same directory as the original image. When clicking on the material, FIX will automatically find this file and perform repairs.
