official benchmark comparison with Construct
As part of Construct compiler documentation, I am making an (official) benchmark comparison with Kaitai. @GreyCat Would you translate this schema to KSY for me? I am asking you specifically, because this is for official publishing. If you can squeeze performance out of it, the better. I added BitStruct because I think Kaitai has actually faster implementation of that one. If you would like to add some fields, even if only because Kaitai has better or faster implementation of those, please just say so.

```py
Struct(
    "count" / Int32ul,
    "items" / Array(this.count, Struct(
        "num1" / Int8ul,
        "num2" / Int24ul,
        "flags" / BitStruct(
            "bool1" / Flag,
            "num4" / BitsInteger(3),
            Padding(4),
        ),
        "fixedarray1" / Array(3, Int8ul),
        "name1" / CString("utf8"),
        "name2" / PascalString(Int8ul, "utf8"),
    )),
)
```
