Added
- Add Dockerfile and docker-compose.yml for development.
- `EncodedSeq.shift`, which will shift sequence by an offset integer.
- `EncodedSeq.from_integer_encoded_seq` will take a list of integers and an
alphabet and return an EncodedSeq object.
- Add the ability to apply a function to the rollout_kmers yielded values.
Changed
- Alphabet special characters are now located at the start, rather than the end,
of the letters and token sequence.
