Add a `y0Accessor` prop for each series to enable the possibility to add a lower limit to area and bars. close elastic#144

This PR adds a `y0Accessors` prop for each `SeriesSpec`: this property can be used to describe a dataset with bands ( with a min and max value for each data point). It's mainly used for with `AreaSeries` to describe a bounded area chart, bounded on the y axis. The `y0` value, is usually a lower value than the `y1`, it will be rendered perpendicularly to the `y1` point. On a standard area chart, the `y0` value usually correspond to `0` or to the previous value in the stack. In a band-area chart, the `y0` can be any value below the `y1` value. It can also be applied to bar charts, with some limitations as described below. On a barchart, the `y0` value is the bottom edge of the bar. On a stacked bar/area chart a series with a `y0Accessor` will be stacked on top of the below series stacking the below series `y1` value with the band series `y0` value. This means that if the below series at a point X has an height of `10`, and the bound series has the following values: `y0: 2, y1: 5` the resulting chart will push the bound series to the top starting using the following values: `y0:12, y1: 15`. The `IndexedGeometry` object is also refactored. To limit amount of redundant code/memory object we used the same `Geometry` elements used on the highlight/hover process. The structure of `IndexedGeometry` is slightly changed, to avoid duplicate values and to simplify tooltip formatting when rendering either y1 and y0 values. I've currently removed from the `indexedGeometries` map all geometry with `null` values on `y1`. This leads to a minor problem: we are not showing any tooltip on that interval, the tooltip of the crosshair is never shown. close #144

Is your feature request related to a problem? Please describe.
Add a band area chart like in the following screenshot.
TSVB currently has this function when using percentile aggregation in band mode.
Describe the solution you'd like
The area chart specification can be extended to add a y0 accessor to specify the minimum value of the area chart if not zero. This will be used to compute the band.
Describe alternatives you've considered
