Implement per-block colour overrides

[ammgws]

This will allow you to override colours on a per-block basis:

icons = "awesome5"

[[block]]
block = "uptime"
[block.color_overrides]
idle_fg = "#00ff00"
idle_bg = "#da11ff"

[[block]]
block = "time"
[block.color_overrides]
idle_fg = "#ff0000ff"
idle_bg = "#00aabbff"

[[block]]
block = "music"
[block.color_overrides]
info_fg = "#0000ff"
info_bg = "#aabbcc"

[[block]]
block = "time"
[block.color_overrides]
idle_fg = "#ff0000ff"
idle_bg = "#deadbeef"

The implementation may be a bit hacky but there doesn't seem to be a better way to achieve this, and I don't foresee the config changing regardless of the implementation in code (so any future rewrites should not break existing configs using block.color_overrides). I would rather have this feature out sooner than keeping users waiting (possibly forever) for a rewrite of the codebase.

It's possible some more work may be required so anyone willing to test this would be greatly appreciated!

This works for me. My use case was to be able to quickly distinguish between the four clocks I have in different timezones:

[[block]]              
block = "time"         
interval = 60          
format = "%T%z"        
timezone = "UTC"       
#colour = "#AAFF88"    
[block.color_overrides]
idle_fg = "#aaffaa"    

# repeat with different colors for different timezones
