Game account parser

The game profile parser is responsible for outputing the user account into the official launcher configuration file.

Initialize the parser

The way to initialize the parser is very simple:

var launcherAccountParser
    = new DefaultLauncherAccountParser(rootPath, clientToken)

Among them, rootPath is the root directory where the core is located (that is, the directory where the .minecraft folder is located). clientToken is a randomly generated GUID.
