Review comment:
In my PR if you use `slicing` method and then write a method to align
bit slices with smth along the lines:
```
unsafe {
let (_, data, _) = self.bit_slice.align_to::<u8>();
let dest = data.as_slice();
}
```
you will get two aligned middle bit domains. then you can check bit slices
however you want to.
