TouchEvent not defined (on Firefox)

[owenmoogk]

Everything works well on chrome, but trying to use react-compare-image on Firefox doesn't work. I get a console error saying:

I think this is coming from line 137 in ReactCompareImage.tsx: if (e instanceof TouchEvent)

On Mozilla, it's also saying that it's not supported on Safari: https://developer.mozilla.org/en-US/docs/Web/API/TouchEvent#browser_compatibility

This might solve it:
