Provide a Maven repository for the Java binding

This repository provides [Java binding](https://github.com/google/libultrahdr/tree/main/java), maybe it would be a good idea to use GitHub Actions to build and bundle native libraries for different platforms and provide them in a Maven repository, [GitHub provides one for each project](https://docs.github.com/en/packages/working-with-a-github-packages-registry/working-with-the-apache-maven-registry)
