When RFC 8974 support (module `nanocoap_token_ext`) is in use, the request token may be longer than the buffer in the separate response context is large. This adds a check to not overflow the buffer. Sadly, this is an API change: Preparing the separate response context can actually fail, so we need to report this with a return value. The example application has been adapted to only proceed if the separate reply context could have been prepared, and rather directly emit a reset message if the token exceeds the static buffer.
