New EventSet.and(), EventSet.or(), EventSet.xor(), EventSet.invert(), EventSet.left_shift(), EventSet.right_shift() operators that implement bitwise operations on integer types, with their corresponding magics: &, |, ^, ~, <<, >>.

and() and or() and invert() are already implemented for bool and need to be extended to work with ints.

Implementation should be factored with base classes so that each operation only needs to define the numpy method it needs to call.

See https://github.com/google/temporian/blob/main/CONTRIBUTING.md#developing-a-new-operator for guidance.

Questions or requests for additional guidance from possible contributors more than welcome!
