Variant Lecterns [Fabric]

Variant Lecterns adds a new Lecterns for each vanilla Plank type.

• All textures have been compressed (without any negative impact) to keep the mod file size to an absolute minimum.
• All textures are manually created using the hex colours from the appropriate planks to ensure they look correct.
• Un-crafting for all variants back to vanilla has been included in case of any issues.
• Vanilla Lectern renamed to Oak and recoloured slightly to better fit the Oak wood type.
