[ADD-SP]

This crate is not an alternative of the serde_json, it only do the validation.

Currently, there is no other crates do the sames validation works on JSON, so I have to parse the dataset by a common JSON parser (sede_json) and do the same validation on its deserialized value as the comparable results.

So it would be better to compare to other crates which do the same work, but I didn't found the similar crate so far. And this is also the reason I developed this crate.
