Modifications to support Java 8 as the minimum requirement #70

Modifications to support Java 8 as the minimum requirement as per JFreeChart 1.5.3.

The build using JDK 8 was broken.

Remove @Deprecated annotation elements not supported by Java 8.
Remove use of Set.of() not supported by Java 8.

Tested on Ubuntu 20.04.05 LTS with OpenJDK 1.8.0_352.

Observed an unrelated fatal OutOfMemoryError when launching the gapless annotation demo chart. Was related to calling XYShapeAnnotation.draw(). This does not occur when running with Java 11 even if built with JDK 8. Will merge but raise a ticket.

I created bug ticket #71 to track the issue.
