[Feature-Request]: Automate OONI Data Download

[Ash-2k3]

Description:

Currently, the script relies on manually downloaded OONI measurement files from the S3 bucket. This manual step hinders automation and requires intervention before each run.

Proposed Solution:

S3 Integration: Integrate boto3, the AWS SDK for Python, into the script.
Automated Download: Implement logic to fetch the latest available web_connectivity measurement files directly from the OONI S3 bucket (ooni-data-eu-fra).
