[Hc747]

• TODO: reasonable default byte buffer allocation size.
• TODO: further reduce packet payload size.
  Reduces container update payload size by a factor of 16.

@Promises @TheBlackParade
Requires a client sided modification.
Can be further optimised.

@Hc747 do you need me to do the client side modifications?

[Hc747]

I’m happy to; can you link the client repo & appropriate place to handle the modification?

The outgoing packet buffer size can be reduced by pulling the packet sizes from the client and using those when creating new packets - search the array for the packet ID and use that size to create the buffer. That was the plan, anyways.

@Promises @TheBlackParade Ready for merging.
