[Vk5-wx-sonde] auto_rx v1.4.0 released

[Mark Jessop]

Hi all,

I've just released v1.4.0 of radiosonde_auto_rx! (This one has been a
long-time coming, apologies for this taking so long!)

This release brings the following changes:
* Starting to deprecate support for Python 2. See notes below!
* Add dynamic KML link to web interface, allowing display of data via
Google Earth. (Thanks drid!)
* Addition of pressure decoding for RS41-SGP sondes. (Thanks rs1729!)
* Improvements in RS41 humidity calculations (Accurate to ~+/- 2.5% Thanks
rs1729!)
* Switch to using timestamps as unique frame IDs for DFM sondes, instead of
the 1-byte frame ID used currently. This resolves some issues observed on
the Sondehub map.
* Fix bug where the Habitat uploader would upload very old telemetry data
if the station's internet connection temporarily failed.
* Fix issue in Meisei IMS100 callsign checking.
* Improve handling of telemetry arriving via a UDP socket.
* Add e-mail notification of failed RTLSDRs.
* Add e-mail notification of nearby landing sondes.
* Add geo links to lat/lon entries in the telemetry table.
* Added an option to set the APRS-IS server port in the config file. The
default has been set to 14590, which for radiosondy.info means that packets
will not be forwarded out to the wider APRS-IS network. Licensed amateur
radio operators can set this back to 14580 so their packets are forwarded.
* Added ability to emit radiosonde humidity and pressure data in APRS
comment fields. The new suggested default aprs_custom_comment value is now:
`aprs_custom_comment = Clb=<vel_v> t=<temp> h=<humidity> p=<pressure>
<freq> Type=<type> Radiosonde`
* Add additional config file checks before allowing custom APRS callsigns.
* Add minimum limits to APRS and Habitat upload rates - please be
considerate of other users of these services and not upload at high rates!


**IMPORTANT UPDATE NOTES:**
* It's now time for all stations to upgrade to Python 3. If your station is
running on Python 2, please either do a fresh install (ideally with the
latest version of Raspbian), or follow the Python 2 -> 3 upgrade guide
here:
https://github.com/projecthorus/radiosonde_auto_rx/wiki/Performing-Updates#upgrading-a-station-from-python-2-to-python-3
* The KML link adds a new python dependency ('simplekml'). This can be
installed by running: `sudo pip3 install -r requirements.txt`.
* If you *really* don't want to do the upgrade to Python 3 just yet, you
can probably get away with just installing the simplekml dependency by
running: `sudo pip install simplekml` (But remember that Python 2 support
will be completely phased out in the near future)
* Due to the changes in the DFM decoder (the frame ID change), we will be
blocking uploads of DFM telemetry to Sondehub from any stations running an
auto_rx version older than 1.3.3 effective immediately. If you are in an
area with DFM sondes, please update promptly, and ensure you re-build the
decoders (e.g. run `./build.sh`)
* The recommended `aprs_custom_comment` value is now: `Clb=<vel_v> t=<temp>
h=<humidity> p=<pressure> <freq> Type=<type> Radiosonde` to best make use
of humidity and pressure decoding improvements.
* If you want your APRS-IS packets forwarded out to the wider APRS-IS
network (outside of radiosondy.info), then you will need to add in the
aprs_port config file option, and set it to 14580. Refer here:
