Feature/client example

[hadijannat]

In this example:

• BASE_URL is the root URL for the API endpoint.
• get_aas_by_id(aas_id) retrieves an Asset Administration Shell (AAS) from the API service by its ID. The function utilizes the requests.get method to perform an HTTP GET request to the API endpoint, and appends the base64url encoded string of the AAS ID to specify which AAS to retrieve. If the server responds successfully (HTTP status code in the 200's), the JSON response is decoded into an AAS object using json.loads() and a custom AASFromJsonDecoder class. The AAS is then returned. If the request is not successful, the function returns None.

Do you want to close this PR? After all we decided to implement the client differently.
