/* CUSTOM DECODE INFO:
args: packet, id/customKE, lpUid (not required)
- decoding the same packet twice will not error anymore
- uid key is returned to every entity
- for every ws you open, it has to be decoded with a seperate id (number or string, no objects) (defaults to -1, used for socket sent by appjs)
- if you want to decode a packet with a custom knownEntities and uid (like a packet that has already been decoded and its not in the same tick), you can pass the customKE as the id and the custom uid as the third argument (this will not update your customKE object!!)
