[FEATURE] Allow using the full date in folder format

[H0tCh0colat3]

Is the feature request related to a problem. Please describe it.

I generally store albums on my hard drive with the following folder format: Artist\[YYYY.MM.DD] Title, however, it's currently impossible (as of version 2.0.5 as best as I can tell) to use any part of the date other than the year when specifying a folder format. (If it matters, I solely use the Deezer functionality.)

Describe the solution you would like.

It would be great if I could specify the date in the folder format, preferably in the format YYYY.MM.DD, but I can make things work with any format as long as the information is there. If for whatever reason a track doesn't have a full date (although I haven't run into such a case on Deezer yet), a fallback to just the year is fine.

Describe alternatives you've considered.

As of now, I need to visit each url in a web browser after downloading and manually add all the dates, which can be a little tedious for dozens/hundreds of albums.
