Issues addressed in this wgh_mods03 branch:

Refactored test_speed1_3.py ookla speedtest code so that the ookla
cli binary reports results in json and test_speed1_3.py parses
the json to populate the speedfile CSV.

This allows test_speed1_3.py to work with any past (and hopefully any
future) version of the speedtest binary.

Further enhancements to logging. A self.Logging message that includes the
word 'exception' now prints a stack trace and the exception information. 

	    ======================================

Latest mod: Checks to see when systemd-timesyncd.service last synced
	    the system time, thereby invalidating our previous
	    ntp-offset query, forcing a new GetNTPOffset()

	    ======================================

This branch, wgh_mods03 has been tested on the LC14 rPi4b, using the
Andi original SDCard installation of the OS and running with no needed
additions or modifications to the system under the crontab entries that
call the scripts in src/scripts.

This fork/branch can be tested on an "Andi Pi" via SSHing into the pi and
substituting this repo/branch for Andi's:

sudo su

cd /home/pi/git

# Stop the running code:
pkill -9 -f 'test_speed1_3.py'

# Save the original andi repo:
mv speedtest speedtest.old

# Clone the Gordon fork, branch wgh_mods03:
git clone --branch=wgh_mods03 https://github.com/gharris999/LCWA.git speedtest

# Generate the keyfile:
cd speedtest/scripts

./lcwa_dec.sh you_know_which_file

# Fix-up permissions
cd /home/pi
chown -R pi:pi .


# Run the code:
sudo -u pi /home/pi/git/speedtest/scripts/restart.sh

# View the logs (requires apt-get install multitail)
