Rebuild cost reduced to 100ms on macbook 15. Build target is always ES6 in dev.

(1) fix bar incremental render (brought by a61fd5ab)
(2) add stream test case.

(1) revert increamental render broken brought by a96d9719
(2) add stream test tools.

fix: (1) move "auto outside stroke" back to zrender. Think that's reasonable to auto provide this strategy to user.
(2) do not specify insideStroke directly, use zrender auto strategry, otherwise incorrect in emphasis.

refact: add mapDimensionsAll. Model use resolveParentPath instead of customizeGetParent for simplicity and performance.
