Applying the key combo system

We would first need to register the origins-kombo:internal power into the powers string array field of an origin JSON for the whole key combo system to work.

The power is used for checking if the player has reached its set max presses, its cast timeout limit, casting cooldown, etc.

Here's an example JSON named test_origin.json stored inside the data/example/origins folder, which has the origins-kombo:internal power registered in its powers string array field:

{
    "powers": [
        "origins-kombo:internal"
    ],
    "icon": {
        "item": "minecraft:white_wool"
    },
    "name": "Test Origin",
    "description": "An origin for testing example kombos.\n"
}
