DVORT licence service

This service answers the activation tool dvort-activate of DVORT for GStreamer. There is nothing to do here in a browser.

On each device, once, with the key from our message:

sudo dvort-activate --key DVORT-XXXX-XXXX-XXXX-XXXX     # the drone, Debian package
./dvort-activate --key DVORT-XXXX-XXXX-XXXX-XXXX         # the drone, user archive
.\dvort-activate.exe --key DVORT-XXXX-XXXX-XXXX-XXXX     # the client, Windows

Without internet on a device: dvort-activate --fingerprint prints its line; send it to us and install the file we return with dvort-activate --install.
