This adds support for having every viewer type implement jsonv2.MarshalerTo and jsonv2.UnmarshalerFrom. This provides a significant boost in performance as the json package no longer needs to validate the entirety of the JSON value outputted by MarshalJSON, nor does it need to identify the boundaries of a JSON value in order to call UnmarshalJSON. For deeply nested and recursive MarshalJSON or UnmarshalJSON calls, this can improve runtime from O(N²) to O(N). This still references "github.com/go-json-experiment/json" instead of the experimental "encoding/json/v2" package now available in Go 1.25 under goexperiment.jsonv2 so that code still builds without the experiment tag. Of note, the "github.com/go-json-experiment/json" package aliases the standard library under the right build conditions.
