Example data does not have element locations.

Some AVO data no longer has separate coordinates for the elements. The examples.py default processing data is an example. I'm not sure if this is an issue with the AVO data. A separate enhancement has been suggested in waveform_collection to flag this behavior.

An example with element location data is here:

SOURCE = 'IRIS'
NETWORK = 'AV'
STATION = 'ADKI'
LOCATION = ''
CHANNEL = ''

START = UTCDateTime('2019-8-13T10:45')
END = START + 10*60

This should be addressed by uafgeotools/waveform_collection#13, and also avoided entirely by fixing the AVO metadata

I've updated the example. The avo metadata are in the process of being fixed. Going to close this for now.
