v5.0.0

• Breaking change: Adding support for rect and polygon
• Breaking change: Allowing textProps to override default offsets
• Breaking change: Fixing incorrect default offsets
• Breaking change: Wrapping nodes and links in a g node for easier transformations

Migrating:

• If you were using circleProps, use nodeProps instead. The format is the same.
• If you were using nodeRadius, instead pass an r prop through nodeProps.
• If you were using nodeOffset, instead pass a dy prop through textProps.
• If you had css selectors relying on the path and g nodes being immediate children of svg, you will have to modify these due to the additional g node inbetween.
• If you weren't using nodeOffset, node text position will change slightly.
