Add missing 3D charts and related layout options

[kMutagene]

This PR adds the 4 missing 3D charts, related Trace objects and layout objects such as the Scene (or adding full support, some are partially there already)

• Add missing params:
  • Scatter3d
  • Surface
  • Mesh3d
• Chart.Point3d (based on existing Scatter3d)
• Chart.Line3d (based on existing Scatter3d)
• Chart.Spline3d (based on existing Scatter3d)(seems not to be possible: Interpolation for 3d data in plotly plotly.py#423)
• Chart.Bubble3d (based on existing Scatter3d)
• Chart.Cone
• Chart.StreamTube
• Chart.Volume
• Chart.IsoSurface
• Full Scene param support
• Chart.withScene to set a 3D scene
• Full ColorAxis support
• Full ColorBar support
• Rework of SubplotID to cover all types of subplots
• Tests
• Docs

A few charts as a preview:

• Cone:

Chart.Cone(
x =[1;1;1],
y =[1;2;3],
z =[1;1;1],
u =[1;2;3],
v =[1;1;2],
w =[4;4;1])

• StreamTube:

lettubeData=
Http.RequestString @"https://raw.githubusercontent.com/plotly/datasets/master/streamtube-wind.csv"|> Frame.ReadCsvString
Chart.StreamTube(
x =(tubeData.["x"]|> Series.values),
y =(tubeData.["y"]|> Series.values),
z =(tubeData.["z"]|> Series.values),
u =(tubeData.["u"]|> Series.values),
v =(tubeData.["v"]|> Series.values),
w =(tubeData.["w"]|> Series.values),
Starts = StreamTubeStarts.init(
X = Array.init 16(fun _ ->80),
Y =[20;30;40;50;20;30;40;50;20;30;40;50;20;30;40;50],
Z =[0;0;0;0;5;5;5;5;10;10;10;10;15;15;15;15]),
ColorScale = StyleParam.Colorscale.Viridis
)

• Volume:

letlinspace(min,max,n)=if n <=2then failwithf "n needs to be larger then 2"letbw= float (max - min)/(float n -1.)
Array.init n (fun i -> min +(bw * float i))letmgrid(min,max,n)=letdata= linspace(min,max,n)letz=[|for i in1.. n do[|for i in1.. n doyield data|]|]letx=[|for i in1.. n do[|for j in1.. n doyield[|for k in1.. n doyield data.[i-1]|]|]|]lety=[|for i in1.. n do[|for j in1.. n doyield[|for k in1.. n doyield data.[j-1]|]|]|]
x,y,z
letx,y,z = mgrid(-8.,8.,40)|>fun(x,y,z)->(x |> Array.concat |> Array.concat),(y |> Array.concat |> Array.concat),(z |> Array.concat |> Array.concat)letvalues= Array.map3 (fun x y z ->
sin(x*y*z)/(x*y*z)) x y z
Chart.Volume(
x, y, z, values,
Opacity=0.1,
Surface=(Surface.init(Count=17)),
IsoMin=0.1,
IsoMax=0.8,
ColorScale = StyleParam.Colorscale.Viridis
)

• IsoSurface:

letxIso,yIso,zIso = mgrid(-5.,5.,40)|>fun(x,y,z)->(x |> Array.concat |> Array.concat),(y |> Array.concat |> Array.concat),(z |> Array.concat |> Array.concat)letvalueIso=
Array.map3 (fun x y z ->
x * x *0.5+ y * y + z * z *2.) xIso yIso zIso
Chart.IsoSurface(
xIso,yIso,zIso,valueIso,
IsoMin =10.,
IsoMax =40.,
Caps = Caps.init(
X =(CapFill.init(Show=false)),
Y =(CapFill.init(Show=false))),
Surface = Surface.init(Count=5),
ColorScale = StyleParam.Colorscale.Viridis
)
