Error in "01. deeptrack_introduction_tutorial.ipynb" from the README tutorials

[james-chow]

Hello,
I've run into an error in the first tutorial, in section 2. Retrieve information about the image. Here it is on Colab:

It appears the "experimental_image" call method is producing an np.ndarray rather than an Image object. Running it locally (on python 3.8) produces the same error for me. Please advise.

@james-chow try and remove the second pair of brackets:

experimental_image.update()() -> experimental_image.update()
