Thanks @sbidari! Some suggestions and a minor but important change for the tests

Pull Request Overview

This PR adds a new function update_hub_target_data() to retrieve and process COVID-19 and RSV target data from CDC sources for hub forecasting. The function pulls data from NHSN (hospital admissions) and NSSP (emergency department visits) datasets, formats them according to hub specifications, and saves them as parquet files.

• Adds the main update_hub_target_data() function with support for COVID and RSV data processing
• Implements comprehensive test suite with mocked API responses for both diseases
• Sets up GitHub Actions workflows for continuous integration and test coverage

LGTM! Minor suggestions you can take or leave. Would be good to have tests for some of the configurable options, but I will leave to you whether to do that here or in a separate PR.
