Authentication Polling, Typed Requests and Client Lifecycle listener

This is the finished release for 5.0.0. It features authentication polling, typed json requests and a brand new League Client lifecycle listener.

Documentation for the new release has been published. The GitHub Wiki has been removed because the documentation is no longer hosted there.

Added

• request<T> will now properly return a Response<T> whose .json() method will return a T (typescript)
• authenticate now has options to awaitConnection, searching until a LeagueClientUx process has been found.
• Running the library on a platform the game doesn't support will now throw an InvalidPlatformError upon calls to authenticate
• LeagueClient is a new LeagueClientUx process lifecycle listener, detecting client shutdowns and startups

Fixes

• Fixed a bug where LeagueWebSocket's subscriptions would attach twice upon registration
• Removed unnecessary fs-extra dependency

Breaking Changes

These changes are not major, but it will end up breaking edge case usage.

• Credentials, the type returned from authenticate no longer returns the HTTP protocol used or the process name. These can always be assumed to be "https" and "LeagueClientUx".
  • This is because the new implementation uses the process command line arguments to retrieve password/port instead of the lockfile process. (see https://www.hextechdocs.dev/lol/lcuapi/6.getting-started-with-the-lcu-api#getting-the-port-number-and-the-password)
• LeagueWebSocket no longer has a getListeners() method, instead, the subscriptions property is now public.
  • The property is no longer an object, the implementation now uses a Map.
