[All] Feat: Delegates listeners

[emyfops]

Feature

Delegates on listeners allow for single self-destroyable listeners to exist.
The following code will return the closest entity to the player once the back input key is pressed.

val closestEntity by receiveNext<MovementEvent.InputUpdate, Entity>(
    transform = { getClosestEntity<Entity>(player.eyePos, 7.0) },
) { it.input.pressingBack }

It also allows to listen incoming events in an unorthodox way.
There are no practical uses outside of unsynchronized multi-threading where value loss is acceptable.

val events by listener<TickEvent.Pre>()
