Subject: [PATCH] print nothing if sensor_sampling_rate is not invertable
The _format_headers() function in IAGA2002Writer.py would choke when
the sensor_sampling_rate parameter in the trace.stats metadata could
not be inverted. This occurred, at least, when the "Digital Sampling"
IAGA2002 header line was not parsed properly, or was blank.
