Added more pilot symbols for precision frequency estimation This adds 4 pilot symbols each after 128 and 256 data symbols. These are used for precision frequency estimation and feed-forward correction, resulting in less decoder errors at the end of the packet. Due to this change, this system can no longer transmit packets shorter than 64 bytes!
