A macro to automatically derive `JsonDeserialize` from
[`core-json-traits`](https://docs.rs/core-json-traits).
This crate can be used quite directly as follows.
```rs
struct MyStruct {
abc_def: Vec<u8>,
}
```
We do support deserializing fields under a distinct name with the `rename` attribute.
```rs
struct MyStruct {
#[rename("abcDef")]
abc_def: Vec<u8>,
}
```
