Recommendation: Create SOP implementation

[vanitasvitae]

Hey!
I can highly recommend creating a CLI implementation of the Stateless OpenPGP Protocol with your library.

By doing so, you can benefit from the OpenPGP Interoperability Test Suite which might help you detect and mitigate interoperability issues.

Hopefully this is something that might interest you :)

Once there is a SOP implementation for flutter-openpgp, the OpenPGP interoperability test suite (https://gitlab.com/sequoia-pgp/openpgp-interoperability-test-suite) can start testing it against many other implementations. This would be good for both flutter-openpgp and the whole OpenPGP ecosystem.
