Code Comment Inconsistency

[YichiZhang0613]

In uint-main/src/bits.rs, the code will panic if index == byte width(in the example is 8), while the comment indicates that code will panic if index > byte width, so I think maybe >= should replace "exceeds".

/// # Panics
    ///
    /// Panics if `index` exceeds the byte width of the number.
/// ```should_panic
/// # use ruint::uint;
/// let x = uint!(0x1234567890_U64);
/// let _ = x.byte(8);
pub const fn byte(&self, index: usize) -> u8 {
    #[cfg(target_endian = "little")]
    {
        self.as_le_slice()[index]
    }

    #[cfg(target_endian = "big")]
    #[allow(clippy::cast_possible_truncation)] // intentional
    {
        (self.limbs[index / 8] >> ((index % 8) * 8)) as u8
    }
}

In uint-main/src/algorithms/div/knuth.rs, the comment indicates that panic if divisor.len()< 2 and numerator.len() < 2, while the code panics if divisor.len()< 3 and numerator.len() < 3

/// Requires
/// * the highest limb of the divisor to be non-zero,
/// * the `divisor` and `numerator` to be at least two limbs, and
/// * `numerator` is at least as long as `divisor`.
///
/// # Panics
///
/// May panic if the above requirements are not met.

pub fn div_nxm(numerator: &mut [u64], divisor: &mut [u64]) {
    debug_assert!(divisor.len() >= 3);
    debug_assert!(numerator.len() >= divisor.len());
    debug_assert!(*divisor.last().unwrap() >= 1);
