- Change `sq key adopt` to not require the key that is being adopted to have a binding signature. - This allows adopting "bare keys," i.e., a certificate consisting of just a primary key. Bare keys are useful when working with raw keys, e.g., keys generated on an OpenPGP card, a TPM device, etc. To add them to a certificate, they just need to be wrapped in a minimal amount of OpenPGP framing; no signatures are required. - Fixes #25.
