Version 2.9.6 pending maven central publication

[pietrygamat]

It looks like we have exhaused the proposed scope of next maven release:
https://github.com/java-native/jssc/pulls?q=milestone%3A2.9.6+
we should go ahead and update jssc version in Maven Central.

The latest 2.9.6 build is now in Sonatype Staging repository pending release to central.
To test with maven, include the following in pom.xml

<project>
     // ...
    <repositories>
        <repository>
            <id>iogithubjava-native-1018</id>
            <url>https://oss.sonatype.org/content/repositories/iogithubjava-native-1018</url>
        </repository>
    </repositories>
     // ...
    <dependencies>
        <dependency>
            <groupId>io.github.java-native</groupId>
            <artifactId>jssc</artifactId>
            <version>2.9.6</version>
        </dependency>
     // ...
    </dependencies>

To test fat jar, download from:
https://github.com/java-native/jssc/releases/tag/v2.9.6

I will postpone the final push for some additional testing - to make sure there were no accidents when rebuilding native libraries.
