Speaks the espp stream_frame v2 protocol (magic "OT" + flags + module + type + len + payload + CRC-32) carrying the USB<->CAN bridge message set on module 5. Works over WebUSB (vendor 0xFF interface) or Web Serial; frames for other modules/types on the stream are ignored so the bridge can multiplex other protocols.
