Source data transmission expansion

[maartenbrinkerink]

I've uploaded the (updated) dataset with costs and losses for transmission lines based on the PLEXOS-World model to the relevant Harvard Dataverse as created for the soft-link work with MESSAGEix-GLOBIOM. Similar to how we do it with the demand file and the PLEXOS-World 2015 model file, a script can now be linked to the raw datafile. Use of the data requires citation of the journal paper (preprint) as mentioned on the Dataverse page. The 'Interface' tab reflects costs per MW.

The relevant Harvard Dataverse is here

The exact download link for the file is https://dataverse.harvard.edu/api/access/datafile/4551443?format=original&gbrecs=true
