reduce amount of excess data produced with totalilator.sh script.

I added checks to stop this script from processing data which was not recorded
during the exhibition's opening times.

Note: The exhibition officially closes on 1st August 2021 but that was a Sunday
and no one was working in Ritherdon that day. This is why the looping range has
been reduced from 6-8 to 6-7.
