Update: Specifications for Payload and Simple Packet.

Add "type" as a recommended Object in the header section for the Payload.

Change the size units being used in Simple Packet.
The numbers used in some areas are completely wrong 2^4 is not 32-bits.
Instead use the word "bytes" or "bits" and update the units.
The Payload Block Structure uses "bytes" rather than bits as that is the general focus of that section.
All others use "bits".
