Deserialization
Import
import ZHWaveform
Create
lazy var waveform: ZHWaveformView = {
let bundle = Bundle(for: type(of: self)) // music
let waveform = ZHWaveformView(
frame: CGRect(x: 0, y: 200, width: view.frame.width, height: 44),
fileURL: bundle.url(forResource: "Apart", withExtension: "mp3")!

wavesColor：wavesColor: UIColor
Cut off the beginning part color：beginningPartColor: UIColor
Cut out the end part color：endPartColor: UIColor
Track Scale：trackScale: CGFloat (0 ~ 1)
Delegate
Create start crop，Valid value is the maxX value of the view：
func waveformView(startCropped waveformView: ZHWaveformView) -> UIView?
Create end crop, Valid value is the minX value of the view:
func waveformView(endCropped waveformView: ZHWaveformView) -> UIView?
Start part of the crop current value:
func waveformView(startCropped: UIView, progress rate: CGFloat)
End part of the crop current value:
func waveformView(endCropped: UIView, progress rate: CGFloat)
