Version 2:
* pack_format now says it works in Mounts of Mayhem update.
* Restructured entire code. Less commands are run to accomplish the same things.
* Added functionality for finding items in:
    * dispensers
    * droppers
    * armor stands
    * campfires and soul campfires
    * suspicious gravel and sand
    * endermen (when they hold items)
* Enchantments:
    * Enchantments and Stored Enchantments are now searchable
    * Just write the id of the enchantment you're looking (eg "feather_falling"), and it'll work the same.
    * Vanilla Minecraft enchantments only.
* Potions:
    * Potions are now searchable.
    * Just write the potion_contents of the potion you're looking for (eg. "swiftness"), and it'll work the same.
    * "swiftness", "long_swiftness", and "strong_swiftness" are seperately searchable.
    * Potions, Splash Potions, Lingering Potions, and Tipped Arrows can all be found.
* Particles:
    * Particle stream consistency now considers quantity of items when the item is in:
        * item entities (dropped items on ground)
        * chest boats
        * chest minecart and hopper minecart
        * donkey and mule
        * llama and trader llama
        * As with containers, if the item is within a shulker box or bundle, particle stream is always weak.
    * Pointing to blocks:
        * When pointing to chiseled bookshelves, particle stream always points to the face you put books into.
        * When pointing to wooden shelves, stream always points to shelf instead of the middle of the block that the shelf is in.
        * For containers, if closest face is obstructed, we use unobstructed faces (in order of closeness) and only don't use a face if all faces are obstructed.
    * A boundary box showing the 21x21x21 volume around the the item finder can be shown.
        * Put an item finder that doesn't have any inscription on any lectern to show it.
        * Item Finder item_display will turn into a lectern with a blue box around it.
* Entities with the invisibility effect are not searched while they have that effect.
* Only the nearest 200 non-empty containers, empty-or-not campfires and empty-or-not suspicious blocks are checked.
* Gamerule max_command_sequence_length is now set to 300k (used to be 160k).
    * Won't change if it's more than 300k when the datapack is loaded.
    * If you find that the Item Finder still isn't working and you're in an area with lots of containers, you can crank it up even more by using the gamerule command.
