Thanks for opening up this PR! Overall it looks good. I wrote down one small suggestion.

Also; I did also notice new codes were added in the meantime. Could you add them as well?

Suggested change

	// from https://en.wikipedia.org/wiki/ISO_15924
	// from https://www.unicode.org/iso15924/iso15924-codes.html

Personally I prefer linking to the more official links instead of Wikipedia. It's fine in the README where more context is useful, but for the actual code this is better for me.

[xDivisionByZerox]

Sure thing. I'm completly with you here. I think I was a bit lazy when I created this PR 😅

I added the missing codes. The dataset is up to date now.

Thanks for your contrib.

However, I'm trying to understand this feature. What would be an example of real-world usage?

[xDivisionByZerox]

At FakerJS we would use this, to verify that our locale metadata have a valid "script" property (defined by ISO-15924) applied to them.

https://github.com/faker-js/faker/blob/489bbc243f3094464888bdf7fb90835fcfa57691/test/locale-imports.spec.ts#L46-L61

Hope this applies for "real-world usage".
