[data-issues] UW.LON bad compression

For UW.LON in the POND for this event, I get an error that looks like  
the data is either badly compressed, or has the wrong compression  
type. The mseed record thinks it is 32 bit floats, but there are not  
enough bytes for the number of points in the record. Other events for  
this station might have this same problem, I haven't looked.

When I try to look at this in wilber, I get an error of "Unable to  
generate plots at this time. Sorry." for this station, so your wilber  
plot generator is probably seeing the same issue.

This is via DHI, but I suspect the problem is in the underlying data,  
not the server.
