Subject: [PATCH] Uninstallation target for CMake

Why:
* Users are requesting uninstallation method
* https://github.com/DanielOgorchock/joycond/issues/93

This change addresses the need by:
* CMake target for uninstall
* An install_manifest.txt is used to revert changes
* Uninstall steps are described in README.md
