Feature request: `clusterplot` use lasso tool in the image and show in diagram

[marabuuu]

Hi @haesleinhuepf,

One more thing about the clusterplot function:
Currently, one can use the the lasso tool in the plot and show the result in the label image.
Additionally, it would also be nice to use the lasso tool in the label image and show the result in the plot.

Best,
Mara

Great idea! In the meantime a workaround: if centroids are measured one can plot x and y and then select objects.

Amd I agree, clicking in the image to see which datapoints are selected would be great!
