Feature Request: Custom System Tray Icons

[ColeTownsend]

Perhaps out of scope for this package, but it would be cool to support custom icon implementations. While currently possible on macOS using custom NSViews, this approach requires manual setup.

In Swift you can do it roughly like below, which I based on this blog

let statusItem = NSStatusBar.system.statusItem(withLength: NSStatusItem.variableLength)
let customView = NSView(frame: NSRect(x: 0, y: 0, width: 30, height: 30))
let arcPath = NSBezierPath()
arcPath.appendArc(withCenter: NSPoint(x: 15, y: 15), radius: 10, startAngle: 90, endAngle: 90 - 270, clockwise: true)
NSColor.systemBlue.setStroke()
arcPath.lineWidth = 3
arcPath.stroke()
statusItem.button?.addSubview(customView)

I think it has more to do with the tray-icon library that Tauri uses or Tauri itself. In the second version of the plugin I put a lot of effort to re-use the tauri api to work with the statusbar, in the first version it would have been more possible than now. But you can fork it and implement any feature you want, you can create a PR, if you have a chance - I will be happy to look at it
