I'm glad to introduce new minor release of id3v2! There is new feature, what is very useful for high-performance tag parsing. And it is id3v2.Options! You can specify, which frames do you want to parse, so id3v2 will not spend time and resources of your computer to parse frames, that you don't need. Or maybe you don't want to parse tags at all, when you can tag, err := id3v2.Open("file.mp3", id3v2.Options{Parse: false}) and that's it!

Also I made possible id3v2 to use in multiple goroutines! Earlier id3v2 had some global elements, so the usage of id3v2 in concurrent programs wasn't possible because of data races to these global elements.
