Making TouchKit Package for the PackageManager

[theGiallo]

If this repo was set-up as a Unity package, it would be possible to add it as git url into the Unity Package Manager. This would make developers life easier. Also I think it could be possible to use it as dependency for other libraries, given the license.

Infos on how to use and implement: https://docs.unity3d.com/Manual/upm-git.html https://docs.unity3d.com/Manual/upm-manifestPkg.html
