feature request: Ely.by auth

[Git-North]

Ely.by auth is the most popular free 3rd party auth/skin service and having an option to login via Ely.by would make this one of the best "crack" launchers

A quick example in my batch file to launch:

--username %mc_username% --version "Fabric 1.20.4" --gameDir "." --assetsDir ".\assets" --assetIndex 12 --uuid %mc_uuid% --accessToken %mc_accessToken% 

For authentication, i post this to get a response like this:

POST https://authserver.ely.by/auth/authenticate
Content-Type: application/json
{"username":"%elyby_username%","password":"%elyby_password%","clientToken":"1","requestUser":false}

{"accessToken":"ELYBY_TOKEN","clientToken":"1","selectedProfile":{"id":"ELYBY_UUID","name":"ELYBY_NAME"},"availableProfiles":[{"id":"XXXXXXXXXX","name":"XXXXXXXX"}]}
