MaLiLib

• fix: failing to save config files when exiting from a server.
• fix: cat variant NBT tags
• remove: 'drawContext' from GuiBase to prevent NPE crashes
• fix: HSV 4-point Color Selector to be more accurate.
• add: DataOps.java for serialization of Data Tags.
• add: InventoryOverlayType.NAUTILUS -- and background slot support; plus Main hand empty slots as a "sword" to help reduce confusion using inv preview.
• add: position_color_lines.fsh
• add: renderTransparencyFix
• further adjust custom shader for Terrain rendering (Litematica) & add ChunkFix Custom UBO to add the Texture Atlas values.

NOTE: Iris will probably need to support this custom UBO in order for the shader's to be correctly shown.
