Title: Tweaks to *Packet constructors

Fixes #21

To create a dummy telemetry packet:
TelemetryPacket tp(NULL);

To create a dummy command packet:
CommandPacket cp(NULL);

I deliberately chose not to implement empty constructors to force the code writer to make clear the intent of the constructor call.
