Fingerprint reader Framework expansion card

In before "redundant" since the 12" Framework doesn't have the fingerprint reader that the 13" does. This would presumably also work on the Desktop, though the expansion slots are in an awkward spot for it.

In the opposite direction, the 13's fingerpint module is sold as a separate part and there's been some past work in adapting it to non-Framework use: https://community.frame.work/t/framework-fingerprint-scanner...
