Feature request: output an error as `json::Value` or `serde_json::Value` directly about miette

[zkat]

miette does not have a dependency on serde_json or similar, and I think it should be up to end users to determine which Value type they want to use. As such, I don't think it's appropriate for miette itself to pull in a dependency like this, when it's trivial to do the parsing yourself. The cost of parsing the string will almost definitely be trivial, because in 99% of cases, displayed errors are relatively low-frequency things (since they're intended for human consumption).

As such, I'm inclined to decline this feature request. I just don't think the cost is worth the benefit.

That's reasonable. I'll close this.
