* add node-fetch and @xboxreplay/xboxlive-auth for microsoft/xbox auth
* decide which authentication to use based on options;
if options.auth === 'microsoft' then use microsoft/xbox auth, else use Yggdrasil until they kill that.
* push working auth
* commentary
* eslint does not like me :(
* User-Agent works just fine without version
* linting = 95% of development
* revert changes to encrypt.js
* set haveCredentials to whether or not we have a token.
Technically this will always be true so...?
* eslint
* mod+create: api + example
* mod: readme.md
* initialize yggdrasil with agent option if it exists
* standardjs
* move require statements to the top
* add agent option to docs and ts type information
also removed useless typescript import and moved class fields from wrong class to the correct one
* update proxy examples and add http agents for proxying yggdrasil
* update to agent supporting yggdrasil version
