Provi's Health Bars

Larger update to provide bug fixes and new data-driven functionality.

Additions

• Added data-driven customisation.
  • Resource packs can now be used to change the hud type, HUD health bars, portrait, and more for individual entity types and also tags.
  • Includes data generators so dependent mods can easily add their own customisations.

Bugfixes

• Adjusted health bar rendering to use vanilla's "text" rendering instead of the prior custom implementation.
  • Resolves the incompatibility with Iris shaders.
  • Should resolve other rendering incompatibilities too.
