Calculates the remainder when `self` is divided by `rhs`.
Returns a tuple of the remainder after dividing along with a boolean indicating
whether an arithmetic overflow would occur. Note that for unsigned integers
overflow never occurs, so the second value is always `false`.
# Panics
This function will panic if `rhs` is zero.
# Examples
Basic usage:
```
# use ::exint::primitive::*;
# ::exint::uint! {
assert_eq!(5_u24.overflowing_rem(2_u24), (1_u24, false));
# }
```
