[Nut-upsuser] Incorrect output.voltage readings : CyberPower AVRG900LCD UPS

[Charles Lepple]

The patch has been merged into the main Git branch, as mentioned here: https://github.com/networkupstools/nut/issues/439 <https://github.com/networkupstools/nut/issues/439> (also suggests why the CP1500... doesn't exhibit the problem)

but a new release is still in the works: https://github.com/networkupstools/nut/issues/1263 <https://github.com/networkupstools/nut/issues/1263>

For reference, CPS UPSes have their own issue tag/label in GitHub, which can help when looking for problems and patches: https://github.com/networkupstools/nut/issues?q=is%3Aissue+is%3Aopen+label%3A%22CyberPower+%28CPS%29%22 <https://github.com/networkupstools/nut/issues?q=is:issue+is:open+label:%22CyberPower+(CPS)%22>
