Add some more detailed testing for radar UF format.

These are currently failing.
correct Month in mesurement time

In UF-file is month stored 1=January, but java Calendar uses 0=January.
At least UTC timezone is recognized
Fix Ray station height.
IOSP: Additional fixes for UF format.

Add handling for figuring out correct end time of the data set. Also add
support for 'GM' timezone as well for UTC. Fix small typo.
IOSP: Fix radar/site name for UF.

The IOSP had been putting out the same information for both 'StationName'
and Station. Disambiguate these terms by using 'instrument_name' and
'site_name' from the CF/Radial spec. Also correct the IOSP to properly
get different entries from the file.
