Ex 04: Query by Time
--------------------
This is an example of converting Voyager_ 1 PWS_ waveform data to power spectral
density in client code.

For long time durations it's more efficent to read dynamic spectra directly
from the server, for example this data source: 
`tag\:das2.org,2012:site:/uiowa/voyager/1/pws/uncalibrated/highrate_spectrogram`_,
however dust hit processing must be preformed on the time-series data directly.
