Review Comment:
Pinot's FunctionInvoker largely depending on the next operator's
FunctionInvoker parameter type casting
(see:
https://github.com/apache/pinot/blob/d1227e466dc6e350214485334cdf4eedc7502d67/pinot-common/src/main/java/org/apache/pinot/common/function/FunctionInvoker.java#L115)
however we are not guaranteed to have another function invoker chained after.
For this i think we can use `functionCall.getDataType()` and try to use it
to convert `_resultType` similar to the link above. (it would have performance
issues but a good starting point)
please comment on the issue and ask for some specific repo examples so we
can add to the test cases
