A type of AudioSource which can be repositioned.
The basic AudioSource just streams continuously with no idea of a current time or length, so the PositionableAudioSource is used for a finite stream that has a current read position.

Creates the PositionableAudioSource.

pure virtual |
Tells the stream to move to a new position.
Calling this indicates that the next call to AudioSource::getNextAudioBlock() should return samples from this position.
Note that this may be called on a different thread to getNextAudioBlock(), so the subclass should make sure it's synchronised.
Implemented in juce::AudioTransportSource, juce::AudioFormatReaderSource, and juce::BufferingAudioSource.
