[Nut-upsdev] New variables?

this is more tied to the input voltage, than the output voltage.
this logic is already handled through the following variables:

- input.transfer.low: Low voltage transfer point (91)
- input.transfer.high: High voltage transfer point (132)
- input.transfer.low.min: smallest settable low voltage transfer point (85)
- input.transfer.low.max: greatest settable low voltage transfer point (95)
- input.transfer.high.min: smallest settable high voltage transfer point (131)
- input.transfer.high.max: greatest settable high voltage transfer point (136)

and

- input.transfer.boost.low : Low voltage boosting transfer point (190)
- input.transfer.boost.high: High voltage boosting transfer point (210)
- input.transfer.trim.low: Low voltage trimming transfer point (230)
- input.transfer.trim.high: High voltage trimming transfer point (240)

cheers,
Arnaud
