[geotrans] Add sources using LFS

[jgsogo]

This works, and it helps us to keep track of sources (git repository stores the sha256 of the file (which is the path in the Artifactory repo)... however, going from the pointer in Github:

version https://git-lfs.github.com/spec/v1
oid sha256:baa72d3b1ae12f237a8ad30f2deb3fed2b80feb759528ea0a72b4b42cb77c565
size 159618792

to the actual URL:

https://c3i.jfrog.io/artifactory/cci-sources-backup/objects/ba/a7/baa72d3b1ae12f237a8ad30f2deb3fed2b80feb759528ea0a72b4b42cb77c565

Requires some manual intervention or internal knowledge about how git-lfs works...
