FB-2041
Added tests for typeIsTimeQuantum and typeIsSet and made them pass.
Added tests for DataTypeTuple cases in typesAreAssignmentCompatible.
Timestamp conversion checking is handled before it gets to that
point but I left those branches in as a backstop.
Checking to see if DataType[String,ID]SetQuantum can be assigned
to themselves doesn't appear to be reachable currently but left
those branches in, because something may use them in future.
Added one test to the DAX skip list since it's the IDSetQ version
of a StringSetQ test that was already on there, changed skip list
to refer to both tests by name instead of by number.
* first time quantum queries working
* implement select from timequantum columns
* skip a dax test
* make linter happy
* addressed review feedback
* reverted over eager test elimination
