Desikan-Killiany Atlas update

[UlrikeS91]

Discussed during an offline meeting with @lzehl

Planned updates:

• Add BrainAtlasVersion representing the parcellation scheme from 2006 (1st version of the atlas)
• Add respective ParcellationEntityVersions for the atlas version (i.e., segmented regions when scheme is applied to MRI scans)
• Update BrainAtlas with some more metadata
• Minor changes to the existing PEs since I found some mistakes when comparing the information from the original publication
• Updates to PEs with some more metadata

One thing besides the comments for license and names in BAV:

I left the license still blank. We can still contact them at some point but until then, we shouldn't assume anything.

Names of BA(V) is change to your suggestion.

• "temporal lobe - lateral aspect" (PE)
• "temporal lobe - medial aspect" (PE)

You avoided everywhere else the "-" in the preferred name but moved this to the alternate names. Could we do the same for these two?

If not: I don't like that the "-" was replaced with an "" in the lookup label and atids (we use "" as separator now for these properties and should avoid introducing them for elements that belong together)

All else looks good :)

The logic was to follow what they have reported in their publication. This was their only exception and the others alternate names with dashes were included in figures or similar. Anyway, I don't mind changing it and it's not making the representation wrong, so I change it to "lateral/medial temporal lobe" with "temporal lobe - lateral/medial aspect" as alternate name (and change all references of this where it is used as parent and in the PT).
