fix: for upsidedown image from oak1

[auphofBSF]

When using the Oak1 in the depthai_demo.py the image is upside down.

 [-cam_model {oakd, oak1}]

The following enables a command line argument to allow specifying the model of camera so as to apply appropriate defaults.

Thank you for the pull request @auphofBSF ! And sorry for the trouble here...

I've created a PR where the depthai library/firmware is modified to auto-detect the OAK-1-PoE device and rotate the camera view accordingly: #474. We should have done this a longer time ago...

An option to manually specify the rotation could still be useful, regardless of the device type, if the user finds it better to mount the device upside down (e.g. for cable management in certain applications).
We could add it, but it would bring a complication for OAK-D devices, when the depth output is used, the calculations would be wrong, as this usecase isn't handled properly yet on firmware side.

Thanks @alex-luxonis , I will pull #474 and test. Would it be useful to change this PR to allow selection by args of any option for setImageOrientation from dai.CameraImageOrientation.* ie: ROTATE_180_DEG.
To handle the Oak-D no support for depth when rotated suggest this ,

# pseudo code - depthai_demo  args for --camera_rotation
if oak-d 
   if arg --disable_depth and arg --camera_rotation
        setImageOrientation derived from arg --camera_rotation
   else:
       log.warn "On Oak-d Camera Rotation not supported when running Depth algorithms"

@auphofBSF that's a great suggestion, will definitely be useful if someone wants to use the demo script for cameras in different orientations

[VanDavv]

@auphofBSF I've added a PR that allows setting the custom camera orientation - #475

#474 works great, thanks @VanDavv. Closing this PR
