  1. feat(clone): enhance type and logic.

    Current `clone()` function considers only those native classes.
    
    - `Date`
    - `Set`
    - `Map`
    - `RegExp`
    
    However, there are much more native classes in the JavaScript, especially about binary handling.
    
    So, I think that the `clone()` function should consider them.
    
    - `Uint8Array`
    - `Uint8ClampedArray`
    - `Uint16Array`
    - `BigInt64Array`
    - `Int8Array`
    - `Int16Array`
    - `Int32Array`
    - `BigInt64Array`
    - `Float32Array`
    - `Float64Array`
    - `ArrayBuffer`
    - `SharedArrayBuffer`
    - `DataView`
    - `Blob`
    - `File`
    
    Also, current `clone()` function is returning the same `T` type with its parameter, but it is not correct.
    
    The returned type must be casted, because non-native classes are converted to primitve object type.
    
    To solve this problem, the `clone()` function needs to return `Shallowed<T>` type like below.
    
    ```typescript
    type Shallowed<T> = Equal<T, ShallowMain<T>> extends true ? T : ShallowMain<T>
    type ShallowMain<T> = T extends [never]
      ? never
      : T extends object
      ? T extends
        | Array<any> | Set<any> | Map<any, any> | Date | RegExp | Date
        | Uint8Array
        | Uint8ClampedArray
        | Uint16Array
        | Uint32Array
        | BigUint64Array
        | Int8Array
        | Int16Array
        | Int32Array
        | BigInt64Array
        | Float32Array
        | Float64Array
        | ArrayBuffer
        | SharedArrayBuffer
        | DataView
        | Blob
        | File
      ? T
      : {
        [P in keyof T]: T[P] extends Function ? never : T[P];
      }
      : T;
    type Equal<X, Y> = X extends Y ? (Y extends X ? true : false) : false;
    ```
