Add clipRRect parameter to WaveStyle

[seelrd]

With this, you can provide an RRect to clip paint with to WaveStyle.
For example:

AudioWaveforms(
                    size: Size(MediaQuery.of(context).size.width, 200.0),
                    recorderController: recorderController,
                    waveStyle: WaveStyle(
                      clipRRect: RRect.fromLTRBR(0, 0, MediaQuery.of(context).size.width,
                          200, const Radius.circular(18)),
                    ),
                  );

This way waveforms can be painted inside a rectangle with border radius.

@seelrd Thanks for your contribution. Can you please share what issue you were facing? Also, if it was with labels then you can pass durationLinesHeight to change height of the line height.

I needed clipRRect to be able to have border radius on wave style lines.
