Feat/support more pg types v2

[dev-void-7]

What is new?

• add support for more postgres types.
• fix some bugs
• add tests for Row extraction
• make the code more consistent (function names and return type)
• handling errors more effectively

New Supported Types:

• Enum
• Range
• Multi-Range

Some Fixed Bugs:

• the zero-dimensional array was returning as JsonValue::Null when it should be an empty array.
• add a buffer length check to the split_at_value_len function.

Add tests to the Row extraction for:

• Simple
• Enum
• Array
• Range
• Multi-Range
• Composite
