Add Advancements API

[p1k0chu]

meh
no tree builder no node stuff just advancements here (means have to manually set the position)
boop:

val root = AdvancementManager.addAdvancement(
    advancement("dockyard:tab1/root") {
        withTitle("<blue>Dockyard")
        withDescription("On github!!!\nDockyardMC/Dockyard")
        withIcon(Items.LAPIS_BLOCK)
        withBackground(Blocks.CHERRY_LEAVES)
        withPosition(0f, 0f)
    })

val advApi = AdvancementManager.addAdvancement(
    advancement("dockyard:tab1/advancements") {
        withParent(root.id)

        withTitle("Advancements API")
        withDescription("Soon! Maybe! Probably!")
        withIcon(Items.PAPER)
        withPosition(0.5f, 1f)
    })

there are toasts (the only reason you wanted advancements)
Player.showToast extension function that takes title, icon and a frame

also event for when player selects an advancement tab

How is this going :3

Are you planning on merging to 1.21.4 still? 1.21.5 will take a WHILE

[p1k0chu]

yes, im not waiting for 1.21.5,
but i kinda want to make advancements just viewable (so you can send them to individual players)
like with a boss bar

+ need to fix stuff, like when deleting an advancement that has children, clients also delete all the children recursively, so need to keep track of that on server-side too

also might actually make advancements mutable now that advancements will keep track of their children (you need to delete advancement and add it again to update properties, and then you probably need to send all the children again)
