Automatic Module Name

Hi. Thanks for an excellent library. I'm currently looking at migration from Java 8 to Java 11 in projects at work and am having issues relating to the module path, especially with the lack of automatic module name for this project. I understand the value of remaining compatible with Java 6, so would suggest that you add an Automatic-Module-Name entry to your manifest-file to make life easier for people using the module path as well as "reserving" a name for future reference.

I'm not well versed in Maven, but I think something like the below would work:
```xml

maven-jar-plugin
2.4



com.flipkart.zjsonpatch

```

Cheers!

Start by reading the Maven build configuration and inspecting the generated JAR manifest. Add the requested Automatic-Module-Name entry using the proposed value, then verify that the built artifact contains that manifest entry and remains compatible with the project's Java 6 target.
