SKLearn regression model with multiple outputs

[johan-sightic]

🌱 Describe your Feature Request

I want to convert a sklearn.linear_model.LinearRegression model with multiple output targets (149 to be exact) but it seems like the converter only supports a single output. This looks like an artificial limitation, is it possible to support multiple outputs?

Describe alternatives you've considered

A multifunction-model is possible but quite annoying to work with. Since this is a simple linear function I think it can be first converted to neural network and then converted that way but this won't work as easily for other models.

Thanks!
