Can't get multiple values for a tag in ID3v2.4

[stkb]

In ID3v2.4, frames can have multiple strings (eg multiple artists), separated by null byte(s). But in the code, the null bytes are stripped from the string before it's passed out, resulting in a string that's just a concatenation of all the values.

Is there a way to get the multiple values for a tag?

The spec [1] is helpfully vague on this, so I'm having trouble working out exactly how this is supposed to work.

If we can be sure it's inline with the spec [1], then I'm happy to make the change/take a pull request to fix it.

Help appreciated!
