This commit introduces significant updates to the device factory system, enhancing the way devices are created and managed within the PepperDash Essentials framework.
The changes include:
- New attributes for device configuration and description.
- Refactoring of the device manager and essentials device classes to support new factory methods.
- modified factory classes for essentials devices, plugin development devices, and processor extension devices.
- The device factory interface has been updated to include a factory method for creating devices.
- Added a wrapper for the device factory to streamline device creation.
- Updated plugin loader to accommodate the new device factory structure.
