How to detect if mobile browser?

[esotericpig]

I'd like to release my game in WebAssembly.

However, if the user is in a mobile browser, I'd like to add some buttons for them to press at the bottom for turning left/right, but I'm not sure how to detect this in Ebiten.

var isMobile = false

func init() {
	ua := js.Global().Get("navigator").Get("userAgent").String()
	isMobile = strings.Contains(ua, "Android") || strings.Contains(ua, "iPhone") || strings.Contains(ua, "iPad") || strings.Contains(ua, "iPod")
}

This should work in 99.99% cases.
