fix(ui): cover art section is hidden on media player when disabled

[suzana2314]

Fixes: #108

Made it so the queue section extends till the bottom. Songs are filled dynamically depending on the height.

This is with the cover art enabled:

and disabled:

Let me know what you think :)

I will also use this pr to ask you something about this queue view.
Does the numbering make sense here? I ask you this because it's static. Take for example this queue:

aaaa
bbbb
cccc
dddd
eeee
ffff
gggg

The current song playing is aaaa
In the media player (when an album art is shown) it will show like this:

Next up
---
1. bbbb
2. cccc
3. dddd
4. eeee
5. ffff

Now song aaaa ended and bbbb is playing, it will show like this:

Next up
---
1. cccc
2. dddd
3. eeee
4. ffff
5. gggg

so now cccc is number 1, but wouldn't it make sense to be like this:

Next up
---
3. cccc
4. dddd
5. eeee
6. ffff
7. gggg

keeping the default queue numbering order? Or just remove the numbering? What do you think?

Hi, thank you for this PR. I have quickly added a fix for the indentation (when going from 9 to 10) and have changed it to the default queue numbering order (your latest overview).

Thank you again for helping improve SubTUI
