Inconsistency: Some items use block textures directly, rather than have dedicated item textures

Some blocks use item textures which are separate from the 3D render of the block they represent. However, a large amount of items still lazily use the raw block texture instead. This makes it unneccessarily difficult to texture the block and item differently as new model files need to be created, and in some cases is actually somewhat of a parity issue as Bedrock Edition has unique item textures for some of these blocks.

The fix is simple: just create duplicates of the block textures and place these in the item folders, and make the item models refer to these files instead. Further tweaking could be done to make their item textures more item-like, and possibly center them better for better visibility in the hand. Alternatively, these items could be made to have 3D item models that more closely match their block form.

Blocks which correctly use unique item textures:

• Lantern

• Soul Lantern

• Campfire

• Soul Campfire

• Chain

• Bell

• Redstone Repeater

• Redstone Comparator

• Dark Oak Door

• Crimson Door

• Warped Door

• Iron Door

• Oak Sign

• Birch Sign

• Spruce Sign

• Jungle Sign

• Acacia Sign

• Dark Oak Sign

Blocks which should be converted to have unique item textures:

• Oak Sapling

• Birch Sapling

• Spruce Sapling

• Jungle Sapling

• Acacia Sapling

Blocks which should be converted to have unique item textures due to parity reasons (these use a constant tint, which is completely unneccessary for an item, as the image file itself can just be directly colored instead - this is how Bedrock Edition does it currently):

• Grass

• Fern

• Tall Grass

• Large Fern

• Vines

• Lily Pad
