Characterization POSTs from 2023 July wrt to MMW

[neilh10]

I collected some system logs from the field for https://monitormywatershed.org/sites/TUCA_Mi03/
Log of real access from TUCA_Mi03 over Verizon cellular
From 2023-07-18 12:11 to 2023-07-31 23:02
This is a system still being commissioned. The sensor reading for depth are invalid. From Aug 1st the LT500 baud rate was changed and now readings are valid

Summary: Over 312 calls with multiple POSTs each call, only 2 calls with POSTs attempts failed. 1) with 504 then 400, and 2) all 400
The other 310 calls all had the POSTs succeed - an amazing improvement over previous periods.

The calls happened to take place at 2minutes past the hour, with 1second pacing between POSTs on the same call.
Most calls had 4 sequential successful POSTs, and a few calls had 8 sequential sucessful POSTs.

This software now logs how long the Modem takes to "connect". Typically 26seconds - showing the power savings to the local system in doing multiple POSTs per call.

This is a follow on from #661
