feat: getKeysPressed() getKeysDown() functions

[candycarmel]

currently, there is no way to "easily" get all keys pressed / down

two functions, getKeysPressed(), and getKeysDown()

they should return arrays of keys pressed, and keys down that frame

[lajbel]

getKeysPressed or getKeysReleased really makes sense? I mean would you use it? At that point wouldn't be better a getKeysState().pressed.has(key)?

[imaginarny]

So for example this is keysDown:

const keysDown = new Set()
onKeyDown(k => keysDown.add(k))
onKeyRelease(k => keysDown.delete(k))

onUpdate(() => keysDown.size && debug.log(...keysDown.keys()))

But keysPressed would be much harder to do and I'm not sure how that would be usable. As those are basically keys that were down on "previous frame" or released, so idk how and when you would use it to match the timing it was pressed, otherwise it would appear empty.

Maybe I understand it wrong. Got any use case or specific reason? Would't be keysDown sufficient as well?
