Tears & Cheers - Ghast Revamp

With the introduction of the Happy Ghast, Ghasts have been updated to have twice the texture resolution. However, I felt like they could've taken advantage of this increased space to give both Ghasts some visual identity, which is why this pack was made!

Changes:
- Both Ghasts now have their eyes lower and further apart, as well as additional subtle detailing, making use of their increased resolution.
- The two Ghasts are now more visually distinct from each other:
- Happy Ghasts have a faint bluish tint to reflect their well-hydrated upbringing. They also look happier and lack tear marks.
- Nether Ghasts look more dry and wrinkly to reflect how the Nether's drought has influenced them. They also look more visibly depressed.
- Dried Ghasts now have a unique item texture

This pack is also compatible with versions before 1.21.6 to just change the texture of the regular Ghast!
