Add support for `dired-fl`

[Yevgnen]

Hi, thanks for the great theme. It would be nice to have support for dired-fl. The default looks not that good in mindre.

I'm on it. I'll have to play around with it for a while though since the point of diredfl is to add colors and the theme is trying to not use a lot of colors.

I've tried a few things, the main issue is that the only reason for diredfl to exist is to make things more colorful while mindre-theme tries to not have very few colors and so adding support for diredfl might almost be pointless simply because it will look almost identical to plain dired.

Anyways, here's what I got:

It could make more sense to make the file-extension color inherit the mindre-type color but I didn't really like it that much.

I'd be willing to make a few tweaks and I'm open to suggestions but I'm hesitant to add a bunch of new colors.

Let me know what you think.
