def string2bin(s, mode="dna"):

• Include in SelexDataset and in PBMDataset a parameter to encode sequences as integers when returning the objects i.e. index_type = int/str
• Declare two tests
  • Test one: load one dataset, encode the indexes as integers, and return that object.
  • Test two: convert the sequences two indexes, the indexes to sequences, and verify that the initial vector of strings is the same as the converted one back and forth.
