> Adding support for new authentication type: user bound SAS
> User-bound SAS (Shared Access Signature) binds a SAS token to a specific user 
> identity rather than just granting access based on possession of the token. 
> This approach addresses key vulnerabilities in previous SAS mechanisms.
> The SAS token for it includes identity-binding parameters (e.g., skdutid, 
> sduoid) that correspond to the user’s Entra tenant and object ID.
> When accessing storage, the user must present a valid Entra access token 
> matching these parameters.
