Add `writeCustomData()` overload

[ghzdude]

What

adds an overload for writeCustomData() that only accepts an id without configuring the buffer

Implementation Details

ideal for when all you need is the id to run logic without needing the buffer

Outcome

a simpler way of syncing to client

[ghzdude]

i'd like to search for usages for this method and see if they can use the new method without issue before this gets merged

[ghzdude]

searching through all usages of writeCustomData(int, Consumer<PacketBuffer>), i only found one that could safely use the new method. ready for review now ig.
