 * SDKCF-5390: **Breaking Changes:** Moved `setDebugLevel()` and `setDebug()` APIs from static to `Logger` class APIs. This will allow multiple SDK app dependencies to have their own debug logging configuration.
   - Deprecated `Logger.setDebugLevel()` and `Logger.setDebug()` static APIs. These APIs will no longer work but not removed to avoid crashes on incompatible SDK versions.
