(I was originally planned to add dataType in click event, but finally modified quite a few files. Did I go too far?)
Add `dataType` to data and `getFormattedLabel` `getDataParams` `graphicEl`.
Enable series to maintain multiple datas (ig: in GraphSeries and SankeySeries).
Enable multiple datas sync when restoreData without trick in Graph.js.
Enable tooltip and click of edgeData without creating special dataModel.

Fix graph transform when has all node same y or same x, Graph node not scale on init(before roam), Optimize roam rect
