<p>This function decodes the received mouse and keyboard actions and acts accordingly. </p>
<pre class="fragment">This function checks if the message received corresponds to a mouse action (left-click, scroll, etc.) or a keyboard action
(such as keypress). It then instructs the laptop to perform these actions, using the 'autopy' and 'pynput' libraries. Some special
characters in keyboard are not supported by 'autopy' library, so the actions corresponding to these special characters are performed
by the 'pynput' library, other key actions are handled by the 'autopy' library. In case of mouse, the 'autopy' library was not that
efficient, so we used the 'pynput' library.</pre>
