Validate bytes when parsing string

[aratz-lasa]

If no validation is done, it can create invalid Multiaddr.
Probably there is an obvious reason for not doing it. So, if it is the case, I am sorry.
As an example, you can create an ip6zone Multiaddr from the following string: ip6zone/. However, if you validate it, it raises an error, because it contains /

ip6zoneStB should validate the string internally. The ValidateBytes function is meant for validating bytes when parsing a multiaddr that's already in the bytes representation.

Could you change the patch to call the ip6zoneVal function from ip6zoneStB?

(we should also document this)

Okay, understood. Maybe it is better to call directly strings.Contains(s, "/")?
Where should we document it?

Maybe it is better to call directly `strings.Contains(s, "/")`?

SGTM.

Where should we document it?

Let's document the functions on the `Transcoder` interface.

Okay, done. I hope it is good enough, tell me if you want to change something.

Thanks!
