System service for Keyman

 Originally created in 1993 to type Lao on Windows, Keyman is now a free and
 open source keyboarding platform which allows anyone to write a keyboard
 layout for their language. Keyman is available for many platforms, including
 Windows, macOS, iOS, Android, Linux and the web.
 .
 Keyboard layouts are defined with a clear and easy to understand keyboard
 grammar. Keyman's contextual input model means keyboard layouts can be
 intelligent and make it simple to type even the most complex languages.
 Keyboard layouts are distributed through an open catalog to all major desktop
 and mobile platforms.
 .
 This package provides a DBus/systemd system service as a helper for
 running Keyman with Wayland.
