1.0.0: Support github/rest-api-description

At this stage, full support is available for github/rest-api-description.

I find the Package plugins to be too slow, and compiling .swift files takes too much time as well. In the future, I plan to:

• Generate Client.swift and Types.swift using the command-line interface (CLI).
• Adopt the XCFramework approach.
  • Reference giginet/Scipio #create-xcframework-from-a-single-swift-package
