Make the sound louder

[GaelleJoubert]

I tried this library on two of my phone, and I feel like even with max volume (volume = 1), the sound is not realy loud. It feels like maybe to sound is generated like in a call, so you have to have you ear on the phone to hear it.

Would it be possible, to make the sound louder, like maybe played like when you phone is on "speaker mode" ? That would be very usefull to me, thanks you very much !

I mannage to make it louder by changing the "max volume" to "100". But I don't know if I should change it in the library ... ?

Here is the code with the change :

private fun playTone(digits: String, durationMs: Int, volume: Double?) {
    val streamType = AudioManager.STREAM_DTMF
    val maxVolume = 100//audioManager.getStreamMaxVolume(streamType)
    var targetVolume = audioManager.getStreamVolume(streamType).toDouble()
    if (volume != null) {
      // Set the volume level as a percentage
      targetVolume = volume * maxVolume// maxVolume
    }

@eopeter should I do a pull request for that ? It does not change the way that you can set the volume, it just change the max volume possible to much louder.
