I was looking at [table_of_contents_header.go](https://github.com/pion/opus/blob/master/table_of_contents_header.go), and noticed that the [Configuration.mode()](https://github.com/pion/opus/blob/6520e40488b7ed311de56047ebd5748f11e73d01/table_of_contents_header.go#L154) method returns 0 if c = 0. According to [RFC6716](https://datatracker.ietf.org/doc/html/rfc6716#section-3), if c = 0, it should be determined to be in SILKOnly mode. Can I fix it?
