Dracula theme for colorls

Hello there,

Thanks for the great job, it makes the developer journey much more valuable !

I wanted to post my personal colorls config that is inspired by the [Dracula color palette](https://draculatheme.com/contribute/#color-palette). These are not the exact same colors as colorls only have a limited colors set, but it's almost that.

Here is the my ~/.config/colorls/dark_colors.yaml:

```config
Main Colors
unrecognized_file: slateblue
recognized_file: snow
dir: magenta

# Link
dead_link: red
link: cyan

# Access Modes
write: cyan
read: magenta
exec: aqua
no_access: indianred

# Age
hour_old: snow
day_old: lightgray
no_modifier: dimgray

# File Size
file_large: snow
file_medium: lightgray
file_small: dimgray

# Random
report: white
user: cyan
tree: cyan
empty: aqua
error: red
normal: aqua

# Git
addition: chartreuse
modification: darkkhaki
deletion: darkred
untracked: darkorange
unchanged: forestgreen
```

Here is a screenshot:


If you know a cleaner way to achieve the same goal, I would be happy to contribute!

Thx

Start with the proposed ~/.config/colorls/dark_colors.yaml content and the linked Dracula palette and screenshot. Inspect the repository's existing configuration or theme conventions, which are not identified in the issue; done would require an agreed way to include or document this palette.
