Error Handling Improvement and Dynamic Memory Allocation

[Suraj7897]

Implement more detailed error handling and logging to provide better insight into why certain addresses fail during the scanning process. This could involve adding error codes or messages to help diagnose issues.

Instead of statically allocating the I2C command handle (i2c_cmd_handle_t cmd), consider dynamically allocating it inside the loop to save memory, especially if the loop iterates through a large number of addresses.
