json-spanned-value

Track the origin of your json values for better error reporting!
The toml crate has toml-spanned-value for this.
serde_json now has json-spanned-value.

The basic crates provide users with a Value type that can be used for custom parsing logic.
However, this type doesn't support span information.
In some cases it's possible to extract line/column information out of error messages,
but that's awkward and error prone - often reporting errors on the next line
(e.g. where the seek position of the underlying reader has skipped to.)
