LWSSSS_LLM_CHANNEL_REQ	Either side proposes to open a new mux channel 0: LWSSSS_LLM_CHANNEL_REQ 1: 1-byte mux channel index, client initiated: first free from zero up, server initiated: first free from 0xff down
LWSSSS_LLM_CHANNEL_ACK	Positive response to earlier LWSSSS_LLM_CHANNEL_REQ 0: LWSSSS_LLM_CHANNEL_ACK 1: 1-byte mux channel index, from the reqyuest
LWSSSS_LLM_CHANNEL_NACK	Negative response to earlier LWSSSS_LLM_CHANNEL_REQ. This also acts as a FIN if one arrives on a channel unsolicited. 0: LWSSSS_LLM_CHANNEL_NACK 1: 1-byte mux channel index, from the reqyuest
LWSSSS_LLM_CHANNEL_CLOSE	Either side informs peer it is closing a mux channel 0: LWSSSS_LLM_CHANNEL_CLOSE 1: 1-byte mux channel index
LWSSSS_LLM_CHANNEL_CLOSE_ACK	Peer acknowledges closing a mux channel, so it can be reused 0: LWSSSS_LLM_CHANNEL_CLOSE_ACK 1: 1-byte mux channel index
LWSSSS_LLM_MUX	Encapsulate data on an open mux channel 0: LWSSSS_LLM_MUX 1: 1-byte mux channel index 2: 2-byte MSB-first rest-of-frame length 4... mux payload
LWSSSS_LLM_PING	Either side wants to validate communication on mux transport 0: LWSSSS_LLM_PING 1: 8-byte MSB-first us resolution unix time this was issued
LWSSSS_LLM_PONG	Either side responds to peer's PING. 0: LWSSSS_LLM_PONG 1: 8-byte MSB-first us resolution unix time from PING 9: 8-byte MSB-first us resolution unix time this PONG sent
LWSSSS_LLM_PONGACK	When the original PING sender receives a PONG, it immediately sends a PINGACK, which is not replied to. This allows the other side to also know the connection is valid in both directions, with only one side needing to issue PINGs. It also synchronizes both sides' understanding of the transport validity in one transaction. 0: LWSSSS_LLM_PONGACK 1: 8-byte MSB-first us resolution unix time from PING
LWSSSS_LLM_RESET_TRANSPORT	Either side can issue this to indicate they no longer trust the transport link. They should close all their channels and enter a state trying to resync using 3-way PINGs
