Attempting to add the results of some polarity analysis work into delta.
Adding a few new polarities, but also removing entries for stations that appear to be incorrectly marked as reversed.
Merged a few entries that should've only been one line.

This should also account for all of the entries in install/streams.csv that were holding up #2613 (comment)

Do we know if HIZ 20 had reversed polarity? It is a strong motion sensor

Should this be compacted into one period as you have done for other stations?

Adding two more stations:
FWVZ: Reversed before 2007-12-22T07:11:08.100000Z
WPVZ: Reversed after 2008-10-28T16:00:03.240000Z

Edit: also condensed some more sequential entries with gaps < a day

Thanks for spotting that, added it in.
Start date is slightly earlier than I have in the ticket, lines up with the reversed SM data

Check where you have added this. I see three rows for OUZ and one for ODZ so I expect a typo in the station code.

It's not a typo, but I messed up my last git commit. It should be there now

The endtime was already in delta, so I left it as is. It belongs to a relatively short-lived datalogger 2008-08-24T23:55:01Z 2009-08-12T23:00:00Z
There's not much data for that install, but it looks reversed enough to be worth keeping:

QRZ Z 2008-08-24T23:55:01Z 2009-08-12T23:00:00Z -0.6278345459668698 43
