Iron Jetpacks

Release 5.0.0 for MC 1.18

Changes:

- Updated to 1.18
- Overhauled how jetpacks are handled internally:
    - Jetpacks are now loaded during resource reload
    - Jetpacks are now synced to the client on resource reload (ex. joining world, /reload)
    - Jetpacks and their crafting components are now differentiated using NBT instead of individual items
    - For using crafting components in recipes see: https://blakesmods.com/docs/ironjetpacks/usage-in-recipes
- Updated default jetpack stats:
    - Added `speedHoverAscend` value, used to set the speed of flying while in hover mode (previous versions used the speedHoverDescend value)
    - Changed `speedHoverDescend` to be the same on all default jetpacks
    - Updated default jetpack colors
- New textures for Jetpack, Thruster, Cell, and Capacitor
