titan: Technical security modules for the VAMGUARD_TITAN project.

Provides standard, well-understood building blocks for an air-gapped IoT
environment:

* ``constants``     -- Shared numeric constants (e.g. FAISS partition seed).
* ``signal_filter`` -- Packet-inspection filter for dropping malformed packets
                       from an incoming IoT data stream.
* ``device_auth``   -- HMAC-based device authentication using a hardware ID
                       supplied via the ``ARK_S10_HWID`` environment variable.
