[chore] bump go-byteutil v1.2.0 -> v1.3.0 (#3356)

* bump go-byteutil v1.2.0 -> v1.3.0 which has safer (as in long-term API consistency) byte <-> string conversions

* fix test relying on byteutil exported type no longer existing

-// Being that the shared fields are in the same struct indices (no different offsets), means that if you have a byte slice you can "forcibly" cast it to a string. Which in a lot of situations can be risky, because then it means you have a string that is NOT immutable, as if someone changes the data in the originating byte slice then the string will reflect that change! Now while this does seem hacky, and it _kind_ of is, it is something that you see performed in the standard library. If you look at the definition for `strings.Builder{}.String()` you'll see this :)
