handle Metashape duplicate the same sensor label with different sensor attributes #86

    Probably I figured out the reason for this bird dataset.

For this metashape project, the doc.xml in Hidden_Little_03_24_2022.files\0\chunk.zip has the following record:

<sensors next_id="2">
    <sensor id="0" label="FC6540, DJI DL   35mm F2.8 LS ASPH (35mm)" type="frame">
      <resolution width="6016" height="4008"/>
      ...
    </sensor>
    <sensor id="1" label="FC6540, DJI DL   35mm F2.8 LS ASPH (35mm)" type="frame">
      ...
    </sensor>

The metashape mistakely duplicated the same sensor to two. And the easyidp assume the each sensor has different sensor label, so use it as the key. So in this case, the sensor 1 rewrite the sensor 0, for sensor object.

There should be a logic bug in idp.Container class which produces sensors object, I will take a look at it on this weekend.

Passed on the ForestBrids dataset:

In [3]: fb = idp.data.ForestBirds()

In [4]: ms = idp.Metashape(fb.metashape.project, chunk_id=0)

In [6]: ms.sensors
