lima.scan_metadata() takes too long
For each acquisition (ct or scans), lima.scan_metadata() gets called. For example, on an eiger camera it takes 1.5 sec !!
Did not find a way to disable it, neither to decide which camera settings needs to be saved for metadata. On some cameras, there might be some attributes for debugging purpose (on pco for example). I do not think we need to systematically include all this
