Add a template for Lua (used by Hyprland since 0.55)

[n0op3]

Since the 0.55 release, hyprlang (Hyprland's DSL) is deprecated for configuring the compositor, in favor of Lua.
I think since pywal16 supports Hyprland pre-0.55, it should continue to support the newer releases as well without the need for user-defined templates.

Here's a complete example of how it can be used in a Lua-based Hyprland config:

package.path = package.path .. ";" .. os.getenv("HOME") .. "/.cache/wal/colors.lua"

local ok, pywal = pcall(require, "colors")

if not ok then
    hl.exec_cmd("notify-send Hyprland 'Loading pywal colors failed'")
    pywal = { color6 = "#ffffff", color4 = "#7C0204" } -- fallback colors
end

hl.config({
    general =
        col = {
            active_border = { colors = { pywal.color6, pywal.color4 } },
            inactive_border = "rgba(00000000)"
        },
    },
})

Or, if the user doesn't care about errors:

package.path = package.path .. ";" .. os.getenv("HOME") .. "/.cache/wal/colors.lua"
local pywal = require("colors")

hl.config({ col = { active_border = { colors = { pywal.color6, pywal.color4 } } } })

Thanks for the awesome project! If any changes are necessary, I'll be happy to make them (I'm not a Python programmer though)
Cheers!

looks good to me
