```
>>> strs = ["foo", "bar", "baz"]
>>> from icy_you import Collator
>>> c = Collator("en-us")
>>> list(sorted(strs, key=c.key_func))
['bar', 'baz', 'foo']
>>> list(sorted(strs, key=c.as_sort_key))
['bar', 'baz', 'foo']
```

Nice to be able to both compute explicit and implicit sort keys! Next up, getting all the optional arguments for strength, case sensitivity, etc.
