FunctionSeries and automatic min/max

[targos]

The problem now with FunctionSeries after these changes is that we have to specifie max,min of vertical axis too

Implementation detail:
how FunctionSeries work?
it take max/ min from horizantal axis if this latter exist and draw lineSeries in [min, max] domain

to specifie max / min we need to either:

• axis max, min props
• or add another series => axis will calculate automatically max, min

=> logically we need just to specifie max /min of horizontal axis to draw it .
but the problem is When Plot is empty

<Plot {...DEFAULT_PLOT_CONFIG}>
      <FunctionSeries
        getY={getY}
      />
      <Axis
        min={0}
        max={20}
        position="bottom"
      />
      <Axis position="left"/>
</Plot>

=> vertical axis domain is not defined => no horizantal axis

i specifie that these are the problems after PR changes

in the current situation, the problem is that when we use FunctionSeries with another Series (that define horizantal axis domain)
the domain will start from 0

the domain here must be [4,8]

[wadjih-bencheikh18]

to fix this issue and also #333
i suggest that we add series type in PlotSeriesState (or a boolean) so that when we calculate max/min we don't take functionSeries in consideration

in order to not change PlotSeriesState i added ~ in functionSeries id
