Update noiseprofiles.h with camera Olympus E-M10

I added lines 1427 through 1450 with the noise profile data for the new Olympus OM-D E-M10.

Zoom centered on cursor: no exception when scale=1
hdr merge: fix a few purple spots

still this is somehow fishy. i don't think the weighting really chooses
the optimal images so far, highlights blow much earlier than the best
input shot.

Fix raw parsing race condition
We get the initial dt_image_t from the database and then read the raw. The settings that come from the raw but not the database are not there. In the past we've papered over this by adding things to the db that have no business being there (e.g., raw_black and raw_maximum). Instead we can swap the correct dt_image_t into the pipeline at the same point we introduce the buffer itself into the pipe. Let the metadata flow together with the data.
Don't keep thumbs if we've dropped the metadata
Since we sometimes need some of the raw metadata from dt_image_t to interpret "thumbnails" (really DT_MIPMAP_F images) we drop them when we drop the metadata. This should be mostly harmless for performance as a lot more metadata should fit than image data, so evictions in the metadata cache should be much rarer.
