-Note that `normalize` (see <https://docs.rs/needletail/0.4.1/needletail/sequence/fn.normalize.html> for what it does) will mutate `self.seq`.
-It is also available as the `normalize_seq(seq: str, iupac: bool)` function which will return the normalized sequence in this case.

 Lastly, there is also a `reverse_complement(seq: str)` that will do exactly what it says. This will not raise an error if you pass some invalid
 characters.
