Use info from unseekable Xing frame when falling back to CBR seeking

This change uses the duration and byte count of the Xing frame, if
they're present, to estimate the bitrate of the stream. The seeking
will still be inaccurate (because we're doing CBR seeking in a VBR
stream), but it will be more accurate than basing the bitrate on the
first MP3 frame we read. It will also mean the duration reported is
accurate.

This change also ensures that if the Xing frame contains the number of
audio bytes but no ToC, the audio data length is still propagated into
the `XingSeeker` (and therefore into the `ConstantBitrateSeeker` too).
