closer to what I want
* setting the temperature just prints it out
* asking for the next time to sample returns a constant (later, it
will read from stdin)
with this, I can wrap this program with `IPC::Run` or similar, and write
all the logic in Perl!
the esp32 will send its own device id with the temperature, and we can
safely assume that the request for "next time" will come from the same
device
