Multiple_accounts.md

It should be possible to use multipe accounts with the following steps:

1. Open Settings -> Integration -> Add new "YouTube Music Player" -> Paste cookie data of the first user
2. The integration will generate a ytube_header.json file in the .storage folder of your configuration, rename this file to something like ytube_header_kolja.json
3. Repeat Step 1 (you can delete the component before, or just have two of them)
4. Repeate Step 2
5. Define the media_player and all input selects twice (source / playlist / speaker / playmode) and directly link them directly as shown below. Suggestion: create two files in the package folder
