[HOT] Kaduna State eHealth Africa Roads import

Hi, Séverin:

Tagging is automatic.

I am working with a script to better join the segments and, therefore,
make the process faster. But it's not trivial, and it's taking me time.

I would suggest to start this import and, when ready, incorporate the
script to the workflow. It would take around 2 months or so with 3
people working full time.

Cheers,

Rafael.
