Additions:
- Added new configuration option to block players from changing spawners using spawn eggs. (New Config Section: https://hastebin.com/luzacefubo.yaml)
- Added Java 8-17 Support.

General Changes:
- Changed the Spawner and Death listeners to now apply Persistent Containers to entities instead of internal maps. This should allow stacker plugins (assuming they clone entities correctly) to work alongside custom PyroSpawner entities.

Fixes:
- Fixed the givebasespawner command not working with amounts in some cases.
- Fixed the giveupgradedspawner command not working with amounts in general.

Notes:
- I am close to finishing the recode of the internals. This will add loads of new features such as MythicMobs support, API support, custom spawn rules, custom spawning, spawner stacking, entity stacking and other cool features.
- I currently do not have a set date for this, but I am currently around 60-70% done.
