- add shit click option to negate a series click in legend
- cleanup partition styles on legend items

This commit fixed the alignment of rect and line annotations near the edge of a data domain. It aligns the x/y position specified by the `dataValues` of the annotation to the domain of the chart.

BREAKING CHANGE: In the rectangular annotation, the y0 parameter of the coordinates now refers to the minimum value and the y1 value refers to the maximum value of the y domain.

fix #586

This commit allows the consumer to configure the direction used for the brush tool. The direction is, by default, along the X-axis, but can be changed to be along the Y-axis or have a rectangular selection along both axes. 
For each Y-axis defined (usually determined by an associated `groupId`) we return a scaled set of `[min, max]` values.

BREAKING CHANGE: The type used by the `BrushEndListener` is now in the following form `{ x?: [number, number]; y?: Array<{ groupId: GroupId; values: [number,
number]; }> }` where `x` contains an array of `[min, max]` values, and the  `y` property is an optional array of objects, containing the `GroupId` and the values of the brush for that specific axis.

fix #587, fix #620
