Describe the bug
If the downloads/modules/packages/ObjectDetectionCoral directory doesn't exist, attempting to download any model results in an error message like this:

17:01:02:Unable to download and install objectdetection-mobilenet-large-edgetpu.zip: Unable to download 'objectdetection-mobilenet-large-edgetpu.zip'. Error: Could not find a part of the path '/app/downloads/modules/packages/ObjectDetectionCoral/objectdetection-mobilenet-large-edgetpu.zip'.

To Reproduce
Steps to reproduce the behavior:

1. Create a fresh CodeProject AI Docker container
2. Download the "Object Detection (Coral)" module
3. Attempt to download models for the Coral module

Expected behavior
Download succeeds

Actual behaviour
Download fails unless I manually create the /app/downloads/modules/packages/ObjectDetectionCoral/ directory.

Same here, but even if I create the 'C:\Program Files\CodeProject\AI\downloads\modules\packages\ObjectDetectionCoral directory, the model download still fails.
