Exa: Different color shades for Date column

[huxi]

Like --color-scale, but for the Date column.

Date levels

• today
• yesterday
• this week
• this month
• this year
• previous years

Good idea

i also like this idea.

in my opinion, k already does this really well, just in case some inspiration is needed:

https://github.com/Peltoche/lsd does this by default; it appears to color files from last year separately as colors from this year, and recent files (maybe past hour?) separately as well. I also like the colors it's chosen for this.
