Histogram2d (#2262)

Implementation of `histogram2d` via already existing functionality of
`histogramdd`.

`histogram2d` accepts 2 different arrays, while `histogramdd` accepts
single two-dimensional array.
In order to avoid double copy (first to single array, second to
supported type) `histogram2d` perform type checks before calling to
`histogramdd`.
