Summary of Changes

Hello @imdominicreed, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request implements a fix within the SDK's LoadTDF function to ensure the KAS session key is correctly and consistently applied during the TDF loading process. By adjusting the timing of when the session key is added to the reader options, the change guarantees that the key is always included in the initial configuration, which is vital for proper TDF decryption and handling.

Highlights

• KAS Session Key Application: The logic responsible for applying the KAS session key (s.kasSessionKey) as a TDFReaderOption has been refactored and relocated within the LoadTDF function.
• Timing of Option Application: The withSessionKey option is now applied earlier in the LoadTDF function, specifically before the newTDFReaderConfig is initialized, ensuring it's part of the initial configuration.

Code Review

This pull request correctly fixes a bug in the LoadTDF function where the KAS session key from the SDK was not being applied to the TDF reader options. By moving the logic to prepend the session key option to before the newTDFReaderConfig call, the change ensures that the session key is properly configured for the TDF reader. The fix is straightforward and improves the correctness of the SDK.
