Baby tokens fuzzer

1. tokenizer are used to split inputs into tokens
2. encoder_decoder will give every new token a new id and record the mapping relation. Then it can convert tokens to EncodedInput, vice versa.
3. encoded_mutations are used to deal with token level mutation, following is the definition: ''' pub fn encoded_mutations() -> tuple_list_type!( EncodedRandMutator, EncodedIncMutator, EncodedDecMutator, EncodedAddMutator, EncodedDeleteMutator, EncodedInsertCopyMutator, EncodedCopyMutator, EncodedCrossoverInsertMutator, EncodedCrossoverReplaceMutator, ) '''
