[ENH] DOBIN transformer implementation

[KatieBuc]

Distance based Outlier BasIs using Neighbors (DOBIN).

DOBIN is a pre-processing algorithm that constructs a set of basis vectors tailored for outlier detection as described by _[1]. DOBIN has a simple mathematical foundation and can be used as a dimension reduction tool for outlier detection tasks.

Currently (only) implemented in R.
