Build from source, and automate publication to `maven`

[Pamplemousse]

From https://github.com/arakelian/java-jq/issues/22, https://github.com/arakelian/java-jq/issues/21#issuecomment-1613340351, I gather that the process of publishing a new version to maven is currently manually done by yourself @arakelian .

Also, *.so files, (supposedly) compiled from source, are vendored in https://github.com/arakelian/java-jq/tree/main/src/main/resources/lib. As a consequence, it takes one to trust maintainers and contributors to not distribute malware.

Leveraging GitHub actions, it would be possible to: 1) build *.so files from source; 2) publish to maven. This would remove the need to trust maintainers and contributors to trust only the build steps and GH action environment. Also, this could simplify the maintenance burden.
