Fix Edge Agent CMD

[AlexGodbehere]

This pull request includes several updates across multiple files in the project, focusing on copyright updates, improved functionality for handling commands, and minor refactoring to streamline the code. Below is a summary of the most important changes:

Command Handling Enhancements:

• Introduced a new optional cmd method in the southbound driver, allowing the handling of device commands with a data object passed as a buffer (lib/js-edge-driver/docs/driver.md, lib/js-edge-driver/lib/driver.js) [1] [2].
• Updated the Driver class to route command messages (cmd/#) to the appropriate handler, ensuring proper processing of device commands (lib/js-edge-driver/lib/driver.js) [1] [2].

Code Refactoring and Cleanup:

• Removed unused imports (fs, sparkplugValue, util, Long) and streamlined existing imports to improve code readability (acs-edge/lib/device.ts, acs-edge/lib/devices/driver.ts, acs-edge/lib/sparkplugNode.ts) [1] [2] [3].
• Simplified writeMetrics in the DriverConnection class by adding logic to find and validate addresses, and to publish payloads (acs-edge/lib/devices/driver.ts).

Minor Functional Updates:

• Added functionality to handle boolean values in writeValToBuffer by writing 1 or 0 based on the metric value (acs-edge/lib/helpers/typeHandler.ts).
• Adjusted a regular expression in the DriverBroker class to handle wildcard commands (cmd/#) (acs-edge/lib/driverBroker.ts).

Documentation and Buffer Enhancements:

• Updated documentation to include details about the new cmd method for southbound drivers (lib/js-edge-driver/docs/driver.md).
• Enhanced BufferX utilities to include methods for converting buffers to JSON and other types (lib/js-edge-driver/lib/bufferx.js).
