A lower-tier, stackable version of the Trident, made from Gypsum. Gypsum spears melee weapons with that can also be thrown. They are fairly weak, and should break after only a couple throws/hits. However, they should be stackable to 16. Due to their lower tier, they will NOT have a 3D held item model - just a 2D texture like a normal item. However, they may get a larger texture and model when held.

Feature checklist:

• Add Gypsum Spear item
• Add Gypsum Spear texture and model and name
• Add Gypsum Spear 32x held item model
• Make Gypsum Spear entity
• Make Gypsum spears throwable with a cooldown
• Make gypsum spears have melee damage
• Set allowed enchantments for gypsum spears to be same as Trident
• Add crafting and advancement for Gypsum spears

I think I might revisit this idea once the reach attribute is added. I think it would be more interesting for spears to modify reach, and not just be a worse copy of tridents.
