Pull request overview

This PR addresses issue #330 where Basilisk's support data files have been moved to a different path in version 2.9.0, causing FileNotFoundError when using BSK-RL with Basilisk installed from wheels. The solution implements a fallback mechanism that tries to use the new Basilisk dataFetcher API and falls back to the legacy path if the new API is not available.

Changes:

• Added try/except import blocks for the new Basilisk dataFetcher API in both orbital.py and world.py
• Updated path construction logic to use the new API when available, otherwise use legacy paths
• Updated release notes to document the compatibility enhancement
