sop: An implementation of the Stateless OpenPGP CLI using Sequoia.

  - This adds a new frontend to Sequoia that implements the Stateless
    OpenPGP Command Line Interface.

  - Compared to sq, sop has a much smaller feature set and hence a
    smaller set of dependencies.  It is less opinionated, and tries to
    faithfully implement the SOP protocol.  We will use it to test
    Sequoia using the OpenPGP Interoperability Test Suite.
