No uninstall entry created

[Cubox]

After installation on Windows, no uninstall entry is created.
While the software is quite light, it is quite a standard by now.

Bonus points if libtap is removed as well (if it is not needed by anyone else)

I don't see how we could know for sure nothing else needs TAP, but we can add an uninstall entry for the software itself at least.
It's terribly documented but looks doable. https://docs.microsoft.com/en-us/windows/desktop/msi/uninstall-registry-key

The TAP part is not mandatory, maybe prompt the user if they want to uninstall it as well?
