Number of asm instructions has decreased (78 -> 59)
The current upstream version contains:
```asm
movabs  rax, 9999999999999999
cmp     rsi, rax
ja      .LBB0_2
```
(if `n > 9_999_999_999_999_999` -> go to panic)
But this function isn't part of the public API, so _I suppose_ we can use `assert_unchecked(n < 10_000_000_000_000_000);`
Similarly, `write_quad` has been moved to a separate fn to reduce duplication slightly
