   In order to implement this feature I would suggest extending `Expr::Not` to work with integral types
   
   https://github.com/apache/arrow-datafusion/blob/8594ec73184b348ba23cf23458f1fc5340505d13/datafusion/expr/src/expr.rs#L104C51-L105
   
   There is already an arrow kernel that can be used: https://docs.rs/arrow/35.0.0/arrow/compute/kernels/bitwise/fn.bitwise_not.html
   
   You may also have to figure out how to get the `~col` to work -- sqlparser supports it -- https://docs.rs/sqlparser/0.32.0/sqlparser/ast/enum.UnaryOperator.html#variant.PGBitwiseNot
