Add file to gapless queue.
public bool AddFile(string FileName, TStreamFormat Format);
All streams added to gapless queue will play without gap between these streams. When one stream ends, next stream from queue starts playing without interruption. Position marker is set to 0 for each stream from queue. This means that when one stream ends, position is set to 0 for next stream. Position is not cumulated.
You can clear gapless queue with Close.
