v0.7.1 - Refactoring of types

This release marks the major enhancement of the internal type system.

• The structs were moved into a better place that aligns with the rest of the code.
• The serialization process now uses a unified buffer instead of concatenating many small buffers.
• I can support complex AND array types.
• There is now a split between table and type which will make transformations easier in queries.
• I have a strong definition of what each layer should be doing.

Known design issues.

• I still have not addressed the lack of well done locking.
• The state of the client is not tracked in regards to in progress transactions.
