This adds year support to the temporal module. Year support is something needed for some TCPH queries. Together with `extract` support apache#9359 we should be able to add `EXTRACT (YEAR FROM dt)` support to DataFusion. Other changes in the PR: * Adding some more tests to `hour` * Removing datatype check from inner loop (there is still one more check in `value_as_datetime` and `value_as_time`) but I leave that for a future PR, as well as further performance improvements (e.g. avoiding the `Int32Builder`, avoiding null checks, adding some microbenchmarks etc.). * Returning an error message on unsupported datatypes (instead of returning an array with nulls). This is backwards incompatible, but I think this is reasonable. Closes apache#9374 from Dandandan/year Authored-by: Heres, Daniel <danielheres@gmail.com> Signed-off-by: Andrew Lamb <andrew@nerdnetworks.org>
