Added support for 0xAARRGGBB

[afonsocraposo]

I typically program Flutter applications using Dart. To define colors, I use Color(0xFF00FF00), in which the color is represented as 0xAARRGGBB. I added support to this color representation in nvim-colorizer.lua, which can be activated using:

require 'colorizer'.setup {
  dart = { rgb_0x = true; } -- enable parsing "0xAARRGGBB"
}

Can this also support 0xRRGGBB?

I also need this not just for dart, for my hyprland config as well
