CAN:MUXED_UNPACK
can:muxed_unpack(Binary payload, Vector params) -> Real

mux_val is the value the mux_mask should yield for this to be the muxed
signal
if unpack(mux_mask)[1] = mux_val then extract signal from payload
CAN:MUXED_UNPACK_SCALE
can:muxed_unpack_scale(Binary payload, Vector params) -> Number val
STABLE
Decode a multiplexed signal in payload.
mux_mask is the unpak formar for getting the mask from the payload
mux_val is the value the mux_mask should yield for this to be the muxed
signal
if unpack(mux_mask)[1] = mux_val then extract signal from payload
according to format, multiply it by k and add c.
