Fix frame dimensions at initialization or when switching simulation mode
Closes #10 (closed)
This MR make sure the frame dim is property setup at start from the Tango property.
- The detector info was not up-to-date with the requested frame size
- Changing the simulation mode is not anymore resetting the frame size
This already fixes the issue.
But i have also reorder the tango simulator initialization to set the mode first, then the frame size. This could be removed from the PR.
With this MR i don't need anymore #10 (closed), cause we can do it by configuration.
