Given an array of strings strs, group all anagrams together into sublists. You may return the output in any order.

An anagram is a string that contains the exact same characters as another string, but the order of the characters can be different.

1 <= strs.length <= 1000.

0 <= strs[i].length <= 100

strs[i] is made up of lowercase English letters.
