Incorporates logic from: Smartthings Zigbee Button for #176.

IMO we just should have a linear volts to % function and each manufacturer/model just need to define the min/Max volts.

@Adminiuga i started the logic found in st for battery logic. #205 But, i would imagine there was a reason ST used the map for some devices... possibly the way they report voltage? I am not stuck on using a map, i honestly just wanted something to get my battery values back as the previous commit made like the bottom 50% of my batteries None.
Both of these PRs are mostly about opening discussion and us getting to a solid fix. Both WIPs. :-)

I like this idea the more that I think about it.

If I can get some ideas how to pass values from the quirks to init I'll get it done.

I just would define a child class overriding parent class attributes for min/max
