Fix the problem when audioFormat's length is zero.
In befor code,
```js
if(opusFormats.length === 0){
        type = StreamType.Arbitrary
        final.push(audioFormat[audioFormat.length - 1])
    }
    else{
        type = StreamType.WebmOpus
        final.push(opusFormats[opusFormats.length - 1])
    }

    if(final.length === 0) {
        type = StreamType.Arbitrary
        final.push(info.format[info.format.length - 1])
    }
```
length of final cannot be 0 coz it only check `opusFormats.length === 0`.
