android11调用相机，调用相册，裁剪图片，anroid10 图片操作工具类
由于是调用系统功能，因此不需权限
PhotoUtils.camera(activity,"你定义的FileProvider的authority"){
uri, success, msg ->
if(success)
Glide.with(this).load(uri).into(binding.ivImage)
}
//调用相册
PhotoUtils.select(fragment){
uri, success, msg ->
if(success)
Glide.with(this).load(uri).into(binding.ivImage)
}
//裁剪图片
PhotoUtils.crop(manager)
.setAspect(1,1)//设置裁剪比例
.setOutput(333,666)//设置输出宽高
.build(uri){uri, success, msg ->
if(success)
Glide.with(this).load(uri).into(binding.ivImage)
}
