parse invalid cbor and continue without exceptions

[jprochazk]

I have a hot-path in my code that every user message goes through. I want to validate every incoming message, and discard it if the message is invalid. Looking through the documentation, there doesn't seem to be an alternative to exceptions. How can I parse CBOR, without using exceptions, but also without aborting, so that the application can continue?

I'm trying to parse CBOR, not JSON, and the interface isn't the same. I don't know how to provide a similar overload for from_cbor.

I believe I found a bug, or at least unexpected(?) behavior. I made an issue #2293
