Cannot run TPC-H benchmark at SF=1000 due to keys larger than 2,147,483,647

[andygrove]

Describe the bug

We use Int32 to represent keys and at SF=1000 we generate values > 2,147,483,647, resulting in errors like this:

Error: ArrowError(ExternalError(ArrowError(ExternalError(Execution("Arrow error: External error: Execution error: Arrow error: External error: Execution error: Arrow error: Parser error: Error while parsing value 3000000002 for column 0 at line 1")))))

To Reproduce
Generate SF=1000 data set and try running queries.

Expected behavior
We should use a more appropriate data type for keys. Perhaps UInt64.

Additional context
None
