Add BEDPE adapter type

[cmdcolin]

Fixes #306

This adds an adapter type for BEDPE files. It creates two SimpleFeature objects for each line of the BED file

1. SimpleFeature with col 1-3 as the primary "location" with a mate field containing columns 4-6
2. SimpleFeature with col 4-6 as the primary "location" with a mate field containing columns 1-3

in this way, these two features "reciprocally point at each other" a little like BND in a VCF file

this is just an initial concept, would be nice to have "arc view" of these features and "breakpoint split view" type stuff, but may need to check support for this

(just for initial assesment the arc display would not work with feature+mate like this, it connects a feature start and end)
