[ETF] Entity Texture Features

[V2.7.0] Betas so far

Various code improvements implemented thanks to @Maximum#8760:

• logging
• iris compatibility
• translation support
• A great deal of source code support and proofreading, thank you again @Maximum#8760

Changed:

• the shader z-fighting fix no longer expands the model leading to weird rendering, emissives should no longer z-fight for most mobs while using shaders.(option has been removed)
• illegal identifier fix changed to only affect image files, cause of litematica conflicts
• names property will also match against the whole line ((names.1=john smith) will check the names {"john", "smith" & " john smith"})

Added:

• Ender Dragon random / custom and emissive texture support
• drowned outer layers support random and emissive textures using the vanilla format
• choice between brighter or optifine-like(default) emissive rendering modes (bright usually provides bigger bloom with shaders and is noticeably brighter in sunlight)
• block entity emissive support for: chests, beds, bells, enchanting table book & lectern book
• block entity random/custom texture support for: chests & beds
• custom lectern book texture support with "minecraft/textures/entity/lectern_book.png"
• emissive shields
• debug logging config option to enable logging relevant ETF mob data when right-clicked
• custom horse armour & markings support, "horse2.png will try to use horse_armor2.png & horse_marking2.png"
• added function to ease access to skin features (a setting in the config/modmenu settings can be enabled to apply a skin feature guide image to a copy of your skin)
• supported emissive and enchanted capes to match skin when set in skin feature choices.
• parrots showing custom & emissive textures on shoulders
• warnings in mod menu config to inform of and prevent mod incompatibilities, as well as an option to ignore these warnings and override them

Fixed:

• memory leak / usage issue in V2.6.0 - was related to entity feature renderer code
• litematica compatibility
• various minor issues
