Pandas support using new API

[wisp3rwind]

The most recent pandas release (0.23) introduces extension types which I believe provide a natural way to integrate pint types into pandas dataframes on a per row/column basis. Is this a feature that could be merged here (assuming no breakage when older/no pandas is installed)?
If so, I'd be interested in researching that possibility further and maybe even implementing it myself. As a disclaimer, I've only started using pint quite recently and am not very proficient with pandas either and I'm not sure when I really get the time to do this. In any case, if someone else beats me to coding the feature, that'd be perfect, too :)

Related issues (which I haven't read fully):

• Consider support for pandas #401
• ENH: unit of measurement / physical quantities pandas-dev/pandas#10349,
• an early user of the new API is cyberpandas

I would be very interested to support this. Maybe you can describe here how you envision this. But I would really like to see this happening.

@hgrecco is this closed as wontfix, works already, or refer to pint-pandas?
