Track number in filename [feature request]

[AndreyMZ]

Tracks in a playlist have an order. When a playlist is downloaded, this order is lost. I suggest to (optionally) save this order by adding a track number in the filename of the track.

For example: 01. Example author - Example title.mp3 instead of just Example author - Example title.mp3

Got it. I'll probably implement a feature to define a track name using predefined variables for available info (such as title, name, etc).

Feature is implemented. For now 3 placeholders are available: #number, #artist, #title

Now the feature works for albums and tracks, but unfortunately it does not work for playlists:

C:\Music>docker run --rm -v "%CD%":/root -it yandex-music-downloader --dir /root --pattern "#number. #artist - #title" --url https://music.yandex.ru/users/strangeislandwithnumbers/playlists/1111 --cookie "<...>"

Also, track number in an album and index number in a playlist may differ. I would like to be able to use the latter one when I download a playlist.
