Status Flags [TOC]
============

In the lecture, it was shown that a bit pattern can be interpreted either as an
unsigned integer or a signed integer. Depending on the interpretation,
addition/subtraction can result in overflow. To detect overflows, the following
status flags should be used:

- `CF` (Carry Flag): Value is `0` when there is no overflow as an unsigned
  integer, otherwise `1`.
- `OF` (Overflow Flag): Value is `0` when there is no overflow as a signed
  integer, otherwise `1`.

Additionally, the following flags are important:

- `ZF` (Zero Flag): Has a value of `1` if s contains only zero entries,
  otherwise `0`.
- `SF` (Sign Flag): Value corresponds to the Most-Significant-Bit of `s`.

Create a module in CircuitVerse named "Status Flags" that determines these
flags based on `a`, `b`, `s`, `Cout`, and `add/sub`. This component can then be
represented as follows, along with the adder:
