extract_hobo.py does not insert if csv has a mix of old and new readings

[matthew-schultz]

If a hobo csv has readings already in the database AND readings that are not in the database, extract_hobo.py will not insert the new readings.

I'm assuming this issue is a reminder that this should be added to the documentation?

[matthew-schultz]

Yeah, unless we wanted to try to update extract_hobo.py to deal with cases like that.

TODO:

Fix issue by updating extract_hobo to use if statement to check if reading.datetime > sensor_info.last_updated_datetime before inserting
