Derives for high performance JSON serialisation and deserialisation.

## Usage

```rust

#[derive(Serialize, Deserialize, Debug)]

#[simd_json(deny_unknown_fields, rename_all = "camelCase")]

struct MyStruct {

    first_field: String,

    #[simd_json(rename = "foo")]

    second_field: Option

}

fn main -> Result<(), simd_json::Error> {

    let my_struct = MyStruct {

        first_field: "i am first".to_string(),

        second_field: None

    }

    println!("Before: {my_struct:?}");

    let mut json_string = my_struct.json_string()?;

    let deserialized = MyStruct::from_str(json_string.as_mut_str())?;

    println!("After: {deserialized:?}");

}

```

## Supported Attributes

Attributes are supported for both `#[simd_json(...)]` and for compatibilty also for `#[serde(...)]` and follow the same naming conventions as serde.

For fields:

* `rename = "new_name"` - renames a field

For structs:

* `rename_all = "camelCase"` - renames all (not otherwise renamed) based on the rule, `camelCase` is currently supported

* `deny_unknown_fields` - Errors if unknown fields are encountered
