Camera overlay capture webWorker

[Umair-Manzoor-47]

Overlay Capture Lag

When trying to capture overlay using web UI becomes unresponsive. apps seems like it's stuck but in fact background image processing is going on.

Solution

Using webWorker for heavy computation and running separate thread for this so UI remains responsive.

EDL:

      - Button:
          label: Custom Overlay widget
          onTap:
            openCamera:
              options:
                captureOverlay: true
                preview: true
                mode: photo
                maxCount: 1
              overlayWidget:

                Column:
                  styles:
                    height: 167
                    width: 250
                    crossAxis: center
                    mainAxis: center
                  children:
