Add a trailing dot/ period after the track number

[Superuser18]

Hi there! Regarding PR #647 for the track number display settings—could we look at adding a trailing dot/period format option (e.g., 01. or 1.) right after the track number?

Right now, without a separator, a track number can blend straight into the song title depending on the font/spacing used on certain screen sizes. Adding an optional toggle or a quick fallback string format like "${trackNumber}." or String.format("%s.", trackNumber) in the song item layout/adapter would keep the text distinctly separated and much easier to read at a glance. Thanks for the awesome work on this feature!

Copied verbatim from my previous response in the PR:

I was tempted to include a separator char, but I did not have references about which one. A dot (.) is one, but a dash (in any flavor: -, –, —) also came into my mind. I also saw a radically different variation that used [ ] to enclosure disk number and number of tracks on disk as well.

This part is what I am interested in addressing right now:

We will need to check how the current feat stands against different kernings to find a proper solution.

In my phone's current font it looks like this.

If the spacing is similar in all phones, a dot would be a good default and there would be no need for a fallback behavior.
How does the spacing look like on your phone?

Thanks for taking the time to look into it. I have 2 android phones and they look identical to what you have posted as a screenshot. The lack of a dot was driving my OCD haywire but if its too much i will try and live with it :)

Implemented in #765.

This should be fixed in the latest release v4.19.0
