This commit mainly focuses on updating the README document. It rephrases some sections to make them easier to understand and removes unnecessary redundancies. The note about networking with Microsoft Flight Simulator is simplified, installation instructions are clarified, information about documentation and samples is adjusted, and descriptions about enum, FSX services, and data definitions are heavily condensed for better readability.
