TODO

When Create Flag is clicked, modify the title to indicate that we are in flagging mode and ROIs can be drawn by dragging.
Update Commit Flag logic:
1. Only commit the flag while in Create-flag mode, selectedData is not null, and a valid flag has been selected.
2. Display the committed flag on the table on the right (replace the current text component).
Record collected flag information initially in a YAML or JSON file. Is this faster than writing directly to the HDF5 file?
Should we actively transfer collected flags by clicking a button?
Enable some form of chunk storage and visualization from the HDF5 file. Iterate over chunks for faster display versus access time.
1. Do I need to modify DIMA?
2. What is a good chunk size?
3. What Dash component can we use to iterate over the chunks?
