JSON support for [Müsli] suitable for network and usually browser
communication.

JSON encoding is fully upgrade stable:

* ✔ Can tolerate missing fields if they are annotated with
  `#[musli(default)]`.
* ✔ Can skip over unknown fields.

```rust
use musli::{Encode, Decode};

#[derive(Debug, PartialEq, Encode, Decode)]
struct Version1 {
    name: String,
}

#[derive(Debug, PartialEq, Encode, Decode)]
struct Version2 {
    name: String,
    #[musli(default)]
    age: Option<u32>,
}

let version2 = musli_json::to_vec(&Version2 {
    name: String::from("Aristotle"),
    age: Some(62),
})?;

let version1: Version1 = musli_json::from_slice(version2.as_slice())?;

assert_eq!(version1, Version1 {
    name: String::from("Aristotle"),
});
```
