2.1.0 - Dependencies upgrade

The dependencies were old and full of CVEs.

Now they are all upgraded to the latest.

Except for JDOM, which would need to be migrated to 2.x. But, JDOM is an abandoned project, and it doesn't make much sense to migrate to it.

Available from Maven Central: https://repo1.maven.org/maven2/ch/zizka/junitdiff/JUnitDiff/2.1.0/JUnitDiff-2.1.0.jar

2.0.0 JUnitDiff revival 2022

Revamped from the original project.
Works with JDK 8+.
Executable jar available also on Maven Central.

Usage:

java -jar JUnitDiff-....jar  path/to/reports/dir path/to/report.xml  ... -o output.html
