This is a NOP for existing usecases. At the moment the only implemented transport for serialized SS is wsi, it's typically used with Unix Domain Sockets, but it also works over tcp the same. It generalizes the interface between serialized chunks and the transport, separately for client and proxy. The wsi transport is migrated to use the new transport ops structs. It will then be possible to "bring your own transport", so long as it is reliable, and in-order, both for proxy and client / sspc. We also adapt minimal-secure-streams-binance to build the -client variant via SS proxy as well. LWS_ONLY_SSPC is added so libwebsockets can be produced with just sspc client support even for tiny targets. A new embedded minimal example for rpi pico is also provided that demonstrates using Serialized SS over a UART to an SS proxy, to implement the SS Binance example on the pico, even though it has no networking itself.
