Subject: [COSE] [cose-issues] Restore “use” COSE key parameter description (#23)

When characterizing key usage for public keys, the two-valued “use” parameter does the job. (The two values are “sign” and “encrypt”.) Restoring it would give COSE functional parity with XML DSIG, JOSE, and the WebCrypto API in this regard. The more complicated and array-valued key_ops is only needed when describing private key usage, which many applications never do.

This issue was previously described on slide 14 of the “COSE Key Issues And Choices” presentation at https://www.ietf.org/proceedings/93/slides/slides-93-cose-7.pdf.
