This PR rewrites the row merging logic to be more correct and improve performance:
- extract row merging logic into its own class to simplify complexity of ReadRows handling
- Use OrderedDict instead of dict() for `{family: { qualifier: [] }}` data, this should maintain serverside ordering (family in creation order and qualifier in lexiographical). 
- define an explicit state machine with states implemented as methods
- add various optimizations like:
  - __slots__ on hot objects to avoid dict lookups
  - avoiding dict lookups for contiguous family and qualifier keys
 
Overall this improves performance by 20% and in my opinion is a lot more readable
