New example raw and hiddenlabel

[lucasferreiralimax]

This PR introduces local storage persistence for the showRaw and hiddenLabel checkbox states, allowing users to retain their preferences across sessions for a more consistent experience. Upon page reload, the selected checkbox states will now be restored, based on the saved values in local storage.

Changes Implemented:

1. Checkbox State Initialization:

   • The showRaw and hiddenLabel states are initialized based on stored values in localStorage.
   • Defaults to false if no prior values are found in localStorage.

2. State Persistence in localStorage:

   • Uses useEffect hooks to save updated showRaw and hiddenLabel states whenever they are toggled, ensuring these values persist in localStorage.

3. UI Update:

   • Adjusted the checkboxes in the App component to display saved user preferences after page reload.
