RevolvedHasselbladOptic does not support multires restoration
This device is in "read only"
scientist have to manually mmount lences to set a magnification.
When multires tries to apply the magnification, it fails.
Problems:
- set magnigfication in this controller expect a list (that's not valid in point of view of the optic inheritance)
- the multires is not aware that this device is read only
- the device should be tagged as read only
- the optic should provide extra parameters that have to be saved by multires to restore the right state
- the multires should display to the scientist that some action have to be done manually
