1.7.0

• Added mermaidType to render() results, parse() models and PeleError that returns Mermaid's type such as flowchart-v2 for graph TD or classDiagram for classDiagram. #30
• parse() now returns ParsedDiagramModel, a DiagramModel with mermaidType. render() still accepts any DiagramModel.
• Chinese and Japanese labels now wrap between characters, so long labels no longer stretch diagrams. Closing punctuation stays on the line it follows. #16
