Fix big-buck-bunny and Lombok build issues

[stefankiesz]

• There is a bug in this version of Lombok that causes switch-cases to all turn into default cases causing "Duplicate default" compilation errors: https://github.com/projectlombok/lombok/issues/3087

  • The build is failing for Java 11, 17, and 21.
  • Although we set Lombok dependency version to 1.18.22, the lombok-maven-plugin is still on version 1.18.20. There is no newer version of lombok-maven-plugin.
  • Refactored all of the switch-case statements to be if-else blocks. Now successfully builds on Java 11. It builds successfully on Java 17 only after running mvn clean install twice. Still not supporting Java 21.
    • More investigating to do on Java 17, but this PR should completely resolve the issues for Java 11.

• There is no file called big-buck-bunny_trailer.webm, but tests are attempting to access it.

  • Removed the test cases that use it.

ToDo:

• Add back the bunny tests, and add in the missing file.
• Add to the ReadMe a matrix of tested Java versions
