[CBOR] allow opting out of hex autodetection

[plexus]

The current design assumes that any string that is valid hex is intended to a binary string. This means it's not possible to encode such strings as regular strings, e.g. "1234".

Would it be possible to make this behavior optional? opt-in ideally, or opt-out.

Thanks.

That is an early design choice as the most useful to my circumstances. Yes I have been bitten by that choice a few times, unlikely scenarios are more common in practice.
Unfortunately(to my knowledge) there is no good typing in emacs to separate a unibytestring and multibyte one. I have sometimes suffered from a string changing between the two during normal use.

I once tried having the byte-string wrapped in a struct. But that complicates the minimal design of this package and to my case, it didn't help much. In the end hex-string and normal string can equally hold information, and that is good enough for me. And if I really need it to be a string some white space padding does the trick for me, way better than anything else.

Of course, feel free to fork the project and give it a try yourself. If I like your approach, I might steal it back into the project. That is the rule of GPLv3.
