Update decoded data table on each new annotation

Currently, the decoded data table only gets updated on 10% steps of the
overall capture time. This slows down updating of the table on long
running sessions, making realtime inspection of e.g. I2C communication
impossible.

Instead of relying on the capture progress, bind the table update to the
annotation generation.
