cer: Download and Tidy Australian Clean Energy Regulator Data

Fetch Australian Clean Energy Regulator data on carbon credits, safeguard mechanism facilities, renewable energy certificates, and greenhouse gas reporting. Provides tidy access to the Australian Carbon Credit Unit ('ACCU') Scheme project register, Safeguard Mechanism baselines and covered emissions, Large-scale Renewable Energy Target ('LRET') power station accreditations, Small-scale Renewable Energy Scheme ('SRES') installation data, the National Greenhouse and Energy Reporting ('NGER') scheme, and Quarterly Carbon Market Reports <https://cer.gov.au/markets/reports-and-data>. Includes a post-Chubb ACCU integrity layer (Chubb 2022 Independent Review), Safeguard reform handling (declining industry baselines from July 2023), National Greenhouse and Energy Reporting scope discipline (Scope 1 / Scope 2 market vs location / Climate Active), reconciliation against the Quarterly Carbon Market Report, and reproducibility helpers (snapshot pinning, SHA-256 cache integrity, session manifest, optional Zenodo deposit).
