-// FirstSentence returns the first sentence found in the given byte slice
-// according to the rules of [Unicode Standard Annex #29, Sentence Boundaries].
-// This function can be called continuously to extract all sentences from a byte
-// slice, as illustrated in the example below.
-//
-// If you don't know the current state, for example when calling the function
-// for the first time, you must pass -1. For consecutive calls, pass the state
-// and rest slice returned by the previous call.
-//
-// The "rest" slice is the sub-slice of the original byte slice "b" starting
-// after the last byte of the identified sentence. If the length of the "rest"
-// slice is 0, the entire byte slice "b" has been processed. The "sentence" byte
-// slice is the sub-slice of the input slice containing the identified sentence.
-//
-// Given an empty byte slice "b", the function returns nil values.
