Go JOSE: Panics in JSON parsing

### Summary Parsing deeply nested JSON structures can hit Go's stack limit, causing the application to crash. Note: this advisory is the same as https://github.com/go-jose/go-jose/security/advisories/GHSA-6mp9-8xrw-74r4. ### Impact Denial of service vulnerability. Any application that parses untrusted JSON via go-jose is exposed. ### Workarounds Reject large inputs before parsing them. ### Acknowledgements Thanks to Dohyun Kim (@azza999), Joshua Rogers of AISLE Research, and Sueun Cho for alerting us to the need to patch this.
