```go
type MarshalerContext interface {
  MarshalJSON(context.Context) ([]byte, error)
}

type UnmarshalerContext interface {
  UnmarshalJSON(context.Context, []byte) error
}
```

### Add DecodeFieldPriorityFirstWin option ( #242 )

In the default behavior, go-json, like encoding/json, will reflect the result of the last evaluation when a field with the same name exists. I've added new options to allow you to change this behavior. `json.DecodeFieldPriorityFirstWin` option reflects the result of the first evaluation if a field with the same name exists. This behavior has a performance advantage as it allows the subsequent strings to be skipped if all fields have been evaluated.

### Support a new feature to compatible with encoding/json

- invalid UTF-8 is coerced to valid UTF-8 ( without performance down )

### Fix encoder

- Fixed handling of MarshalJSON of function type

### Fix decoding of slice of pointer type

If there is a pointer value, go-json will use it. (This behavior is necessary to achieve the ability to prioritize pre-filled values). However, since slices are reused internally, there was a bug that referred to the previous pointer value. Therefore, it is not necessary to refer to the pointer value in advance for the slice element, so we explicitly initialize slice element by `nil`.
