GeekCamera2 手动调整ISO

UI Setup

MainActivity#cameraSetup
  |--> final SeekBar iso_seek_bar = findViewById(R.id.iso_seekbar);
  |--> iso_seek_bar.setOnSeekBarChangeListener(null);
  |--> iso_seek_bar.setOnSeekBarChangeListener(new OnSeekBarChangeListener()

UI调整ISO流程

MainActivity#iso_seek_bar#onProgressChanged
  |--> Preview#setISO
    |--> CameraController2#setISO
      |--> CameraSetting#setAEMode
          |--> CaptureRequest.CONTROL_AE_MODE to OFF
          |--> CaptureRequest.SENSOR_SENSITIVITY to iso
          |--> CaptureRequest.SENSOR_EXPOSURE_TIME to exp_time
          |--> CaptureRequest.SENSOR_FRAME_DURATION to sensor_frame_duration
