Original GitHub issue: https://github.com/sigma67/ytmusicapi/issues/711

Seems like youtube music recently added the ability to add custom images to playlists! Can we extend create_playlist() and edit_playlist to take an optional argument (an image file) so that we can programmatically set it?

before that call^ there was a call to

https://music.youtube.com/playlist_image_upload/playlist_custom_thumbnail?upload_id=AFiumC58THIgewkszL0aq8xbBLW1PSC-notrwUIrOnWDEkxSt0PDPf52HNC8x3xv7XIe1zwBXqOfCA6Ox9mW4dOF_KeC_YCzYro5hbDqGPe9UA&upload_protocol=resumable

with the payload containing the image data (my guess). and the response was

{
  "encryptedBlobId":"65jVDxiw9NQXhgph-9IlssToi-FoBdg68actYIIMK-vjU2o5Gq8QvK5H9PkpmMVZvtP7jQspWqJhprOnmyp1aQ=="
}

the same blobid passed to edit_playlist

and before that call^ was an empty request call to https://music.youtube.com/playlist_image_upload/playlist_custom_thumbnail

that returned

x-goog-upload-url:
https://music.youtube.com/playlist_image_upload/playlist_custom_thumbnail?upload_id=AFiumC58THIgewkszL0aq8xbBLW1PSC-notrwUIrOnWDEkxSt0PDPf52HNC8x3xv7XIe1zwBXqOfCA6Ox9mW4dOF_KeC_YCzYro5hbDqGPe9UA&upload_protocol=resumable

in the reponse headers - which probably gives us the URL to call while uploading the image

This should be implemented in edit_playlist only. When an optional image Path is provided, the upload is performed via separate calls to

https://music.youtube.com/playlist_image_upload/playlist_custom_thumbnail

which returns an encrypted blob id, which is then wrapped in a corresponding action for the edit_playlist call.
