Remove internal JASPAR database and use the JASPAR2014 pacakge

[matthuska]

Currently we include a copy of the JASPAR database inside the data/ directory. It would be nice to remove this and just rely on the JASPAR2014 R package, so that we don't have to update it ourselves.

Hi, we (@Partinabox) are trying to make use of the JASPAR2018 package, however, I am not sure how to get the data in the appropriate form (Lits of matrices) to get it working with the rank.factors function.
Any advise on that?
