[Python script] Create fake alerts thourgh the API

Current Behavior

The only alerts created for development purpose are created by the false cameras (you can check cameras' behavior here : https://github.com/pyronear/pyro-envdev/issues/10).
But the the timestamp of the alerts are set by the engine which means :

1. we cannot create alerts in the past
2. all the alerts will be attached to the same Sequence object in the API database (which means a Wildfire) because we need to have a pause of 30min between two alerts in order to create a new Sequence.

Wanted Behavior

We would like to be able to create Detections with a python script, using the /detections/ POST endpoint of the dev env API (documentation here)

In order to link the detections to an existing cameras you will have to generate a token thankts to the endpoint /cameras/{camera_id}/token. For that you can hardcode camera_id=1 for the static camera and camera_id=2 for the ptz camera.

• No need to containerized the script, you can use the localhost:5050 url.
• You can use these images saved in a new directory

No repository file or test is named. Start with the linked /detections/ POST documentation and the /cameras/{camera_id}/token endpoint, using localhost:5050 and camera IDs 1 and 2. Done means a Python script uses the release images to create detections with controllable past timestamps and associates them with the existing cameras.
