/*
  API for importing instances from other launchers
  launcherType can be one of the following:
  - MultiMC
  - GDLauncher
  - ATLauncher
  - Curseforge
  - PrismLauncher
  - Unknown (shouldn't be used, but is used internally if the launcher type isn't recognized)

  For each launcher type, we can get a guess of the default path for the launcher, and a list of importable instances
  For most launchers, this will be the application's data directory, with two exceptions:
  - MultiMC: this goes to the app directory (wherever the app is)
  - Curseforge: this goes to the 'minecraft' subdirectory of the data directory, as Curseforge has multiple games
