Moved house to annotation

This repo has moved house from Dans-labs to
annotation, a new organization.

The reason is that we have separated the TF apps from the TF core.
Before, the apps were part of the TF repo, now they have their separate repos.

Yet we still want apps and core under one organisation, until both mature further.

The Dans-labs org hosts many unrelated repos,
so for the sake of clarity we put TF and its apps under a new, dedicated organization.
