subset_points not working for interactive plots

Hi!

First of all, thank you so much for this amazing library.

I have noticed a little issue while plotting a subset of points with interactive plots.
In the function interactive of umap/plot.py [LINE 1268]
instead of:

points = umap_object.embedding_
    if subset_points:
        points = points[subset_points]

I think it would be better to just use:

as you do in the points function:

if subset_points is not None:
        if len(subset_points) != points.shape[0]:
            raise ValueError(
                "Size of subset points ({}) does not match number of input points ({})".format(
                    len(subset_points), points.shape[0]
                )
            )

        data = data[subset_points]
        if hover_data is not None:
            hover_data = hover_data[subset_points]

Thanks

Start in umap/plot.py at interactive around line 1268 and compare its subset_points handling with the points function. Check how the subset is applied to points, data, and hover_data, including the existing input-size validation. Done when interactive plots handle subset_points consistently without mismatched input errors.
