feat: Add sequential swap methods

Browse Source 
- Add some basic tests (will add more in next commits)
- Adapt sequential tests (which originally tested split swap)
- Adapt a forgotten single swap test

TODO:
- Fix encoding of single and sequential swaps to not expect the split sawp format every time (the split and the token indices are not necessary and consume unnecessary gas).
