Add Monitoring container to MC data

[FrancaCassol]

Waiting for a better solution concerning the handing of Monitoring data in ctapipe, I propose to change the DataContainer() in simteleventsource.py with an EventAndMonDataContainer() .
This should permit to test the calibration tools with MC data following the same procedure used for real data.

Is the idea then to later fill the mon containers from simulations?

[FrancaCassol]

Exactly.

Hi @kosack,

could you please merge this PR?
Thanks

This only exchanges the class of this container in the SimtelEventSource.
It does not fill it.

What is the reason, the the mon field is not just added to DataContainer?

the container will be filled by the calibration scripts (as for the data).

I made this choice to separate the event and the monitoring level. As said, this
is surely not the final/better solution, but it works fine at least at R1 level.
