WPMZManager: lost or missing data

Hello,

I'm using `WPMZManager` to read, modify, and save mission files. I'm creating some missions in the DJI Pilot 2 app, exporting them to read/modify in my app, and then reimport them back to Pilot 2 app.

WMPZ SDK Version: `com.dji:wpmzsdk:1.0.1.5`. (I did not find any newer versions)

MSDK version: 5.9.2

When using `WPMZManager`, I'm experiencing the following issues:

1. Unable to get `templateType`

When reading mission files using `WPMZManager.getKMZInfo(path)`, `KMZInfo` object is returned, which contains the `Template` object without `templateType` field. Internally, `WaylineTemplate` object is used which contains `templateType`, but it's transformed to `Template` for `KMZInfo`. I need this info to know if the mission is 'waypoints' or `mapping2d` etc. Is there a way to get around this and get access to `templateType`?

2. When `templateType == "mapping2d"` there are boundary coordinates in the `template.kml` under  

      <Placemark>
...
        <Polygon>
          <outerBoundaryIs>
            <LinearRing>
              <coordinates>
                 (coordinates I would like to access)
              </coordinates>
            </LinearRing>
          </outerBoundaryIs>
        </Polygon>
      </Placemark>

Is there a way to access the coordinates above?

3. Mission data is changed when loaded and saved

 If I load mission files using `WPMZManager.getKMZInfo()` and save them using 

WPMZManager.generateKMZFile(String kmzPath, WaylineMission waylineMission, WaylineMissionConfig config, Wayline wayline)

WPMZManager.generateKMZFile(String kmzPath , WaylineMission waylineMission , WaylineMissionConfig config , Template waylineTemplate)
