Implemented query to retrieve all image URIs for a given camera within a certain time derived from the target prediction time

Tested by manually creating image entity entries in the DynamoDB table:

Image 1 that should be returned:
- PK: camera#camera_1
- SK: image#1703157100
- URI: camera_1/image_1_include
Image 2 that should be returned:
- PK: camera#camera_1
- SK: image#1703150100
- URI: camera_1/image_2_include
Image that should not be returned, as it is too old
- PK: camera#camera_1
- SK: image#1703149900
- URI: camera_1/image_3_ignore
Image that should not be returned, as it is from another camera
- PK: camera#camera_2
- SK: image#1703157100
- URI: camera_2/image_4_ignore

Called Lambda with input: { "predictFor": 1703157200, "cameraId": "camera_1" }

Returned result: { "1703150100": "camera_1/image_2_include", "1703157100": "camera_1/image_1_include" }
