Use String.prototype.normalize combined with Unicode property escapes

Hey,

First of all, thanks for the lib! It saved me a lot of headaches.

I've been trying to handle diacritics using the following solution:

const normalize = (str: string) =>
  str
    .normalize("NFD")
    .replace(/\p{Diacritic}/gu, "")

It works pretty well, but it doesn't do exactly what normalize-diacritics does because it won't replace ł with l or đ with d, as it only handles diacritics.

Still, it covers the vast majority of cases that normalize-diacritics handles using the hardcoded array of Unicode characters.

So, the idea here is that the library code could be simplified by using the String.prototype.normalize API combined with Unicode property escapes to cover most cases and handling the remaining cases with the current lookup array.

It could potentially also improve performance.
