Convert MiniSEED time series data to SAC

 SAC and MiniSEED are two commonly used formats for seismological data.
 .
 mseed2sac converts MiniSEED waveform data to SAC format. The output SAC
 file can be either ASCII or binary (either byte-order), the default is
 binary with the same byte-order as the host computer. By default all
 aspects of the input files are automatically detected.
