data generation for workloads greater than 100T

[balaby25]

hi,
It is amply clear that the current tpcds tools codebase supports few discrete workloads until 100T.
But, for a test case, i need 250T dataset - even though i know we cant use it for official results.
i tried modifying few lines of code in scaling.c - to generate 250T but, it doesnot generate any .dat files.
may i know which files/lines of code i need to change to generate a working dsdgen and dsqgen for 250T?
