[FR] Ability to retrieve additional metadata about App

[n8felton]

When using mas to automate gathering information about Apps, it would be nice to be able to retrieve additional metadata such as the Description, "What's New", and Category (and potentially all the other metadata available in the "Information" section of the MAS)

Describe the solution you'd like An updated command such as mas info or additional argument such as mas info --description and/or mas info --full to include additional App metadata

Description: Xcode includes everything developers need to create great applications for Mac, iPhone, iPad, Apple TV, and Apple Watch. Xcode provides developers a unified workflow for user interface design, coding, testing, and debugging. The Xcode IDE combined with the Swift programming language make developing apps easy and fun.

Xcode includes the Xcode IDE, Swift and C/C++/Objective-C compilers, Instruments analysis tool, simulators, the latest SDKs, and hundreds of powerful features:

Innovative tools help you create great apps
• Swift is an intuitive programming language that is safe, fast, and modern
• SwiftUI is a revolutionary framework to create user interfaces with a declarative Swift syntax
• Playgrounds are a fun way to experiment and interact with Swift code
• View debugging shows a 3D stack of all your app's UI view layers at runtime
• Split editors in virtually unlimited ways, show previews, or choose an assistant to see related content
• Live issues display errors as you type, and Fix-its improve your code with just a click
• Source control navigator and service integrations help you manage code across a team

SwiftUI and Interface Builder make it easy to design your interface
• SwiftUI uses declarative Swift code that clearly describes your interface
• Design canvas graphically builds UI views using the library of controls and modifyers
• Preview SwiftUI code or UIKit interfaces in different screen sizes, orientations, and font sizes
• SwiftUI code is always in perfect sync with the graphical design canvas and previews
• Animations are built using simple commands that describe the action you want to see

Professional editor and debugger keep your code front and center
• Refactoring makes it easy to modify the structure of Swift, Objective-C, C, and C++ code
• Open Quickly instantly opens any file within your project
• Data tips and Quick Look can inspect a variable by hovering your mouse over code while debugging

Instruments for performance analysis
• Compare CPU, disk, memory, and GPU performance as graphical tracks over time
• Identify performance bottlenecks, then dive deep into the code to uncover the cause
• Analyze your app directly, or sample the entire system with very little overhead
• Create custom instruments with unique visualizations to analyze your own code and frameworks

To test or run applications on an iPhone, iPad, Apple TV, or Apple Watch all you need is a free Apple ID. To submit your apps to the App Store you must be a member of the Apple Developer Program. Some features may require Internet access.
Whats New: Xcode 12.5 supports iOS 14.5, iPadOS 14.5, tvOS 14.5, watchOS 7.4, and macOS Big Sur 11.3

New in Xcode 12.5
• Playgrounds documents can access symbols within the current app target
• Simulator can record videos of your app and export the video as an animated GIF
• Swift improves incremental build time performance
• watchOS apps gain improved support for automated testing
• Localization workflow can export all projects within a workspace into a single catalog
• Code signing performance is improved for complex projects
• Additional bug fixes and stability improvements

It probably makes sense to implement this as part of #190.

[phatblat]

My thoughts exactly, @chris-araman. For context, @n8felton, changing output format can break scripts and tools that parse mas output. Perhaps we can combine this idea with #190 as we add more output and flags to control the format.
