feat: example app draws rectangles

[cdiddy77]

A bunch of changes all piled in together to get the objectdetection example working more

• fixup the ci.yml : for now just use the hash of examples/objectdetection since we notice that the hack that chatgpt proposed didnt really work. This will need to be revised when we have multiple examples
• hack to prevent crash when developing on android. tracking issue
• disable building the old example
• small hack to get the size of the image being processed as part of the inference results
• android fix to handle frame processing before we have finished initializing the object detector
• use react-native-skia to render a labeled rectangle for each detected object.

@dwgray when this gets merged, example will not be receiving any typechecking or linting. Subsequently it will be deleted entirely.
