Toggle Annotations visibility in plot_raw()

If working with heavily-annotated data, it can become very difficult to tell overlapping Annotations apart, and their descriptions may overlap too – see e.g. this example based on the sample data:

I’m now intending to add EOG, ECG, and artifact Annotations to this dataset, but I’m already struggling to keep track of what’s going on 🧐 Of course I could shrink the displayed time span, but this may not always be a feasible approach.

I wondered if we could offer an option to toggle visibility for each annotation individually? When in Annotations mode, we already display a window with radio buttons to select which Annotation(s) to add / modify. Could we maybe simply add checkboxes – probably left of the radio buttons – to toggle visibility?

Yes, although not all file formats support this.

A tooltip doesn’t seem too bad from a picker standpoint I guess. But the overlap is still going to be a problem in that case.

A checkbox in the annotations window to disable at least the labeling, maybe also the annotation itself (maybe two check boxes then?) would be a good first step. @drammock up to you
