decide on splitting the change in two and have the current branch only for introducing rel_gain_mode and next branch for replacing rel_gain with rel_gain_mode to have one parameter only

final changes related by differentiating between module index and module numbers. This should all be replaced with CALCAT metadata

1.Plot agipd single module geometry for correct and darks
2.Fix sorting dark runs
3.Fix reading a single module which doesnt start at 0

- replace np.percentile(, [0,100]) with min(), max()
- put back histogram plots with get_range for no need of change.
- improve gain plot and add clamp function

- Remove int conversion for integration_time
- Move allocating constants in sharedmemory to loading constants cell

1. Remove when dictionary from notebook and from agipdlib
2. Improve cell filling time-summary table
3. Remove uneeded function and defined parameters in agipdlib.py

1. Move Initialize_from_db to the notebook
2. Remove function and it's test from cal_tools
3. Use CalibrationData Latex table displaying constant timestamps
4. Start storing data in fragment file
5. Avoid errors in case Thresholds or Noise were not retrieved.
6. Update and cleanup cell for adding timing summary

- Remove precorrection notebook
- Remove function retrieving constant from YAML
- Use fragment file
- WIP: start moving constant retrieval function to the notebook
