get Lock State
Sends a GET_STATE (0x5A) command to the lock.
For example, a response might look like 00, 02, 00 where:
00 means the command completed successfully.
02 represents the lock's current state (e.g., Lock Closed).
00 indicates the last change in lock status occurred without any problems. A LOCK_STATUS value of 01 indicates an error (LOCK_STATUS_ERROR_JAMMED), meaning the lock was jammed during the last attempt to change its state.
