Create nonconvex TopographySurface, Revit API

[Revitalizer]

Please let us create TopographySurface Elements that can have concave edges.

As of now (Revit 2018), there is just this method which always returns a convex hull:

public static TopographySurface Create(
    Document document,
    IList<XYZ> points
)

I suggest to add something like this:

public static TopographySurface Create(
    Document document,
    IList<XYZ> points,
    IList<CurveLoop> boundaries
)

This way, one could except areas from the convex hull, like applying a mask to it.

It would be good if function have ability for having Breaklines.

Since Revit 2020 (2019.2, exactly), there is a new method

TopographySurface Create(
	Document document,
	IList<XYZ> points,
	IList<PolymeshFacet> facets
)

which can be used to define a concave topo mesh.

So I think this issue is solved now.

@Anonymous: thank you!
