tonihei 81e7b31be1 Apply playback parameters in a consistent way. 
Currently, we sometimes apply new playback parameters directly and sometimes
through the list of playbackParameterCheckpoints. Only when using the checkpoints,
we also reset the offset and corresponding position for speedup position
calculation. However, these offsets need to be changed in all cases to prevent
calculation errors during speedup calculation[1].

This change channels all playback parameters changes through the checkpoints to
ensure the offsets get updated accordingly. This fixes an issue introduced in
31911ca54a.

[1] - The speed up is calculated using the ratio of input and output bytes in
SonicAudioProcessor.scaleDurationForSpeedUp. Whenever we set new playback
parameters to the audio processor these two counts are reset. If we don't reset
the offsets too, the scaled timestamp can be a large value compared to the input
and output bytes causing massive inaccuracies (like the +20 seconds in the
linked issue).
