Draft: fix: CUE file data parsing in playlist

Note: Since the duration of the last track in a CUE file could not be parsed due to the lack of a stop time, the start time of the last track has been stored as an intermediate value. Finally, this intermediate value is subtracted from the total length of the audio file to calculate the duration of the last track.

Sample CUE file: soft-rock-CD.cue
