Jim Schaad had stored private keys in JSON for testing in places like:
    https://github.com/cose-wg/Examples/blob/master/ecdsa-examples/ecdsa-01.json

This may be of some utility: https://test.webpki.org/csf-lab/cosekey
For testing purposes only of course :)

AFAIK, there is no equivalent CBOR encoding for this.
At least not one that I could easily find in the COSE documents.
