Tracking: Which TPC-H queries can be run?

Related: #11, #68, #127

Ran with no datafusion optimizations (all of our own optimizations)

Tests were done for whether or not the query works with perfbench. Query result may be incorrect, but it compiles and runs

also note that we didn't test if the query plan we generated is correct -- for now it is possible that we generated a plan that doesn't run in DF, or generates wrong result.
