Explore how to keep track of brightness and contrast adjustments when user is labelling

[hannahker]

The modified brightness and contrast information could be useful to input into training.

• How can we keep track of adjustments to these settings and associate them with individual annotations?
• What's the most appropriate way to store this data?

[danton267]

We will add relevant information to the dcc.Store object next to every annotation

"annotations" {
image_slice_id: [
{ "brightness": x, "contrast": y, "zoom": z, "annotation-object": []

and then have a simple function that takes this object and prepares it for the figure when switching between image slices.

This will also allow for simple read/write/update to a database once that is implemented.
