MCRGB - A Colour Picker for Blocks

Changes in v0.3.3:

• Further improved load times since v0.3.2. Reading and writing colour info to a JSON file is now entirely optional, and off by default. With the "Read Colour Info from JSON File" option set to "No", MCRGB will always get it's information directly from the game's textures, significantly improving load times, especially on large modpacks.
• Added a scrollbar to the texture thumbnails in the Block Info GUI. This only affects blocks with a large number of textures which would previously spill into other parts of the GUI, such as the Monitor block from CC: Tweaked.
• Added a config option "Maximum Tooltip Lines", which now defaults to 15. This is to avoid overly large tooltips when hovering over items in the MCRGB GUI, or in the inventory with "Show Block Colours in Tooltips" set to "All Contexts"
• When scanning textures, or reading/writing JSON, MCRGB now records the time taken and writes it to the Minecraft Log for debugging purposes.
• Also includes changes from v0.3.1 and v0.3.2 which were previously unavailable for Minecraft 1.21.1
