Support 1.19

[Electroid]

Now that we support Spigot 1.8, we should look at supporting Spigot (or Paper?) 1.19. My hunch is just supporting 1.8 and the latest version will be easier than supporting every possible version between 1.8 and 1.19. It's possible that enough APIs have been added to 1.16 that reflection is not necessary in that version, but there may still need to be a few NMSHacks.

Part of this work will be to change the pom.xml version of Bukkit to 1.19 and change SportPaper APIs to use reflection, likely with SportPaperUtils.

Paper 1.16+ has native support for adventure, so there are several benefit/performance reasons why we may want to target Paper. (about 50% of servers use Paper according to recent stats, and it's going up)
