command: add audio-pts property to get the audio pts 

For audio files, this is identical to time-pos (except read-only).
For audio-video files, this returns the audio position. Unlike
time-pos, this is not quantized to a video frame.
For video-only files, this property is unavailable.

Remaining length of the file in seconds. Note that the file duration is not
always exactly known, so this is an estimate.
``audio-pts`` (R)
Current audio playback position in current file in seconds. Unlike time-pos,
this updates more often than once per frame. For audio-only files, it is
mostly equivalent to time-pos, while for video-only files this property is
not available.
``playtime-remaining``
``time-remaining`` scaled by the current ``speed``.
