ENH:  Series between inclusive pair (GH: 12398)
- [ X  ] closes #12398
- [ X ] tests added / passed
- [ X ] passes `git diff upstream/master | flake8 --diff`
- [ X ] whatsnew entry

Amends pandas.Series.between method to set different inclusive/exclusive endpoints.

inclusive : Boolean to indicate whether or not to include both the left
            and right endpoints (True: a <= series <= b, False: a < series < b),
            or an iterable boolean pair to set them separately, e.g
            inclusive=(False, True) for a < series <= b.

I guess. pls add some doc-string examples

use `closed='left'|'right'|None` like we do for `DatetimeIndex`

```
closed : string or None, default None
    Make the interval closed with respect to the given frequency to
    the 'left', 'right', or both sides (None)
```
 up pls update for 0.18.1. pls also create a new issue to deprecate `.between` (and i'll mark for 0.19.0)
 closed in favor of #13027
