librespot: Command line arguments are incorrectly echoed in TRACE.

See this output:

The part that says -3 belongs to the argument before that.

The argument is parsed correctly, because the other part of the log is correct:

[2021-12-05T12:11:25Z DEBUG librespot_playback::mixer::alsamixer] Alsa forcing linear dB mapping: false
[2021-12-05T12:11:25Z DEBUG librespot_playback::player] Normalisation Type: Track
[2021-12-05T12:11:25Z DEBUG librespot_playback::player] Normalisation Pregain: -3.0 dB
[2021-12-05T12:11:25Z DEBUG librespot_playback::player] Normalisation Threshold: -2.0 dBFS
[2021-12-05T12:11:25Z DEBUG librespot_playback::player] Normalisation Method: Dynamic
[2021-12-05T12:11:25Z DEBUG librespot_playback::player] Normalisation Attack: 5ms
[2021-12-05T12:11:25Z DEBUG librespot_playback::player] Normalisation Release: 100ms
[2021-12-05T12:11:25Z DEBUG librespot_playback::player] Normalisation Knee: 1.0

So it seems only the echo is incorrect. Minor error, but could be fixed whatsoever I believe.
