ChirpStack V4 incompatable (with suggested fix)

[robert-stevenson-1]

Trying to use these with a v4 chirpstack instance on a ntoher device and get codec errors.
added:

// ChirpStack v4 wrapper
function decodeUplink(input) {
    return {
        data: Decode(input.fPort, input.bytes, input.variables)
    };
}

// --- Your existing Seeed Studio code starts below here ---

This resolved my issues when testing a S2103 sensor.
Open to other sensor testing.
This should hopefully maintain backwards compatibility too, but I would need someone else to test that
