Added options to DTSC pull for controlling the buffer config. Made 8X target duration the default buffer size. Inputs now wait for INPUT_TIMEOUT *and* two biggestFragment durations, added a few helper functions to DTSC::Meta. Buffer now automatically sets segment size to min(configed_size, biggest_fragment/2) to prevent sudden reductions of fragment sizes by more than 50%
