option_protocol value is -128..127
Stream[4] to [25] = Channels or failsafe depending on Steam[0]

0 -125%
204 -100%
1024 0%
1843 +100%
2047 +125%
Values are concatenated to fit in 22 bytes like in SBUS protocol.
Failsafe values have exactly the same range/values than normal channels except the extremes where
0=hold, 2047=no pulse. If failsafe is not set or RX then failsafe packets should not be sent.

/*
Multiprotocol telemetry/command definition for OpenTX
Based on #define MULTI_TELEMETRY enables OpenTX to get the multimodule status and select the correct telemetry type automatically.
Serial: 100000 Baud 8e2 (same as input)
TLV Protocol (type, length, value), allows a TX to ignore unknown messages
Format: header (4 byte) + data (variable)
[0] = 'M' (0x4d)
[1] = 'P' (0x50)
The first byte is deliberatly chosen to be different from other telemetry protocols
(e.g. 0xAA for DSM/Multi, 0xAA for FlySky and 0x7e for Frsky) to allow a TX to detect
the telemetry format of older versions
[2] Type (see below)
[3] Length (excluding the 4 header bytes)
[4-xx] data
Commands from TX to multi cannot be longer than 22 bytes (RXLen -4byte header)
Type = 0x01 Multimodule Status:
[4] Flags
0x01 = Input signal detected
0x02 = Serial mode enabled
0x04 = protocol is valid
0x08 = module is in binding mode
0x10 = module waits a bind event to load the protocol

[8] patchlevel,

more information can be added by specifing a longer length of the type, the TX will just ignore these bytes
Type 0x02 Frksy S.port telemetry
Type 0x03 Frsky Hub telemetry
*No* usual frsky byte stuffing and without start/stop byte (0x7e)
Type 0x04 Spektrum telemetry data
data[0] RSSI
data[1-15] telemetry data
Type 0x05 DSM bind data
data[0-16] DSM bind data
technically DSM bind data is only 10 bytes but multi sends 16
like with telemtery, check length field)
Type 0x06 Flysky AFHDS2 telemetry data
length: 29
data[0] = RSSI value
data[1-28] telemetry data
Type 0x0A Hitec telemetry data
length: 12
data[0-10] telemetry data
