Splits the string into a lazy sequence of substrings, alternating between substrings that match the patthern and the substrings between the matches. The sequence always starts with the substring before the first match, or an empty string if the beginning of the string matches.
For example: (re-partition #"[a-z]+" "abc123def")
Returns: ("" "abc" "123" "def")
