feat: bitwise not

[milancermak]

Feature Request

Describe the Feature Request

So far, there's no support for bitwise not in Cairo 1. Cairo 0 offered a bitwise_not function. Rust has ! that uses the Not trait. Cairo 1 already declares a Not trait, so what's missing is only the implementation of it on the appropriate types.

Describe Preferred Solution

let some_bits = 27_u8; // 0b11011
let not_some_bits = !some_bits;
assert(not_some_bits == 228_u8, 'nope'); // 228 == 0b11100100

sounds like a nice idea - although my c++ sensitivities confuses me in this case (! always sounds boolean to me, not bitwise) - we should ask around a bit around this before deciding (was a bit surprised myself that rust does work that way)
