Hex support for colors

[Fusezion]

I'd love to see hex color support added to this extension sadly I'm not skilled enough to create/edit extensions or understand nearly enough how to but what I can do is offer the json and regex.
<#ff00ff> and <##ff00ff> due to skript formatting

here's the regex and json for it

{
"match": "(?i)(\\<#*#[a-f0-9]{6}\\>)",
"name": "skript.color.hex"
}

while I was testing the regex I couldn't get a valid check with the \\ but I'm guessing that's nothing important
as all the other syntax in syntax.json uses it.
maybe removing the support for 1 of # would be good as skript wouldn't accept it anyways and instead would return an error
