* This is a breaking change because it changes the signature of `Argument#parse`, but most use cases should not be affected.
Support has been maintained for the old argument map signature, so only completely custom arguments will be affected.
* **breaking** [Placement rule api changes](https://github.com/hollow-cube/minestom-ce/pull/20)
* Optionally use reworked chunk sending algorithm (`minestom.use-new-chunk-sending` system property)
