Hey folks :wave:

while deserializing (implementing `KSerializer.deserialize`), is there a way to get access to the “raw” value of a primitive? As a string, for example. Since JSON numbers don’t have to be floating point numbers (by the standard <https://www.json.org/json-en.html>, although some implementation do assume that they are all double, unfortunately), I need a way to read fractional numbers from JSON without compromising their precision (to convert them to some decimal type, for example), none of the existing `Decoder` can do that it seems. Am I missing something?

One option would be to write such values as strings server-side, but 1) it’s not always feasible to change existing endpoints that are just fine 2) one doesn’t always control the API.

**UPD** found an issue, apparently it’s not possible atm: <https://github.com/Kotlin/kotlinx.serialization/issues/1405>

same question goes for serialization, is there a way to write arbitrary bytes as a JSON value?
