Adds circuit board connections, quick connections to ComfyUI

• To install, go to ComfyUI manager -> look up "quick-connections"
• Demo

How to use...

• Don't block the output / input areas.
• Give it some room. If the connections have no room to move, it'll get confused.
• There is no insert dot in the middle of the connection. Drag the output to an empty spot, add a new node, and drag the output of the new node. Sorry.
• Can be disabled in options under "Quick connections", "Circuit Board lines"

Can be used with litegraph too. See example folder.

To run examples...

npm install
python -m http.server
