Add reverb effect on playing sound

[nakane11]

Dependency

pip install pedalboard pedalboard can work on Python 3.6 or above.

Sample

• window 1 $ roslaunch soundplay_node.launch

• window 2 (Invoke python)

  import rospy
  from sound_play.libsoundplay import SoundClient
  
  rospy.init_node('soundclient_example')
  soundhandle = SoundClient(blocking=True)
  soundhandle.say('Say-ing stuff while block-ing')
  soundhandle.say('Say-ing stuff while block-ing', reverb=0.5)
  soundhandle.say('Say-ing stuff while block-ing', reverb=0.9)

  I confirmed the sample, but haven't written the dependency yet.
