Platform IO library

[sschueller]

Please consider publishing this library to Platform IO so it can easily be used in Platform IO projects. This allows for automated updates, complex version pinning etc. without having to download a zip every time. It also reduces the size of project repositories as external dependencies do not need to be in the projects VCS.
