'null' tags returned for correctly tagged file... ?

Hi,

I'm trying to create a small app, using webpack, with an audio file located in my project folder. Here is my code:
```
import fs from 'fs'
import id3 from 'id3js'

tagReader: () => {
id3('./../data/test.ogg', function(err, tags) {
console.log('tags: ', tags)
})
}
```

I checked the file which is correctly tagged (it is an .ogg), but for some reason I can't understand, all properties remains 'null'... Someone having the same issue, and/or able to give me some help? Thnak you in advance!

The issue is about reading ID3 tags from an OGG file, but the library may not support OGG format. Check the library's supported formats in the README or source code, and examine the id3js module's parsing logic. Look at the test suite for examples of reading tags from different file types. Verify the file path and encoding, and see if there are existing tests for OGG files.
