This endpoint will emit a presigned URL to which to upload the file.

The actual upload must start within one minute of the initial call, and terminate within 15 minutes.

The HTTP client used must then replay the request to the provided URL with the same headers as the initial request except for
the Marble API key, and upload the CSV file.

For Marble's hosted platform or when using Google Cloud Storage, adding the header indicated here (x-goog-if-generation-match: 0)
is mandatory. For self-hosted deployment, refer to Marble's documentation to learn more about requirements, depending on the
blob storage in use.
