Bitwise operators -band, -bor and -bxor

Implemented bitwise operators -band, -bor and -bxor

```powershell
0x0F0F -band 0xFE
0x0F0F -bor 0xFE
0x0F0F -bxor 0xFE
```

The tests have been added as reference tests.
Moved the implemented case statements up so the NotImplementedException is thrown for the rest.
