Works on the signed-in person's songs, or on a song saved without an account if you pass its claim_token. The melody must have no errors.

`create_song`Saves a melody as a new private song. The melody must have no errors (run validate_melody or fit_melody_to_box first); warnings such as notes repeated too quickly are saved and marked, as in the composer. If the person is signed in, the song goes to their account and you get a link to open it in the composer. Without an account the song is saved anonymously and you get a claim link: give it to the person so they can keep it (valid 30 days). Set save_to_my_account to true to ask the person to sign in first (apps that cannot sign in mid-conversation should save without an account and give the claim link instead). Limits: 5 songs a day without an account, 15 a day with one.	Saves a melody as a new private song.
