Provide system binaries

[DeflatedPickle]

For those who don't have a Java 8 runtime enviroment and for those that don't care about having access to the library JARs, it would be useful to have system-specific binaries, built and released via GitHub Actions. As I can't settle on a single way to make a native binary, one will be provided for every JVM binary-making tool with a Gradle plugin
