telem-volts.py requires python2 and obsolete library

[matt-domsch-sp]

While clearly just included as a demonstration of capabilities, the telem-volts.py script requires python2 and a now-obsolete Adafruit_ADS1x15 library. Fedora 33 has deprecated python2 in favor of python3, and per [1] the adafruit library has been replaced with https://circuitpython.org/blinka.

What is the upstream author's intent for telem-volts.py? As a distribution packager, should I simply move this file to docs?
