#duration ⇒ `Object`

Oggs require reading to the end of the file in order to calculate their duration (as it’s not stored in any header or metadata). Thus, if the IO like object supplied to WahWah is a streaming download, getting the duration would download the entire audio file, which may not be desirable. Making it lazy in this manner allows the user to avoid that.
