GHSA-H7H7-6MX3-R89V Fyrox has unsound usages of `Vec::from_raw_parts`

The library provides a public safe API transmutevecasbytes, which incorrectly assumes that any generic type T could have stable layout, causing to uninitialized memory exposure if the users pass any types with padding bytes as T and cast it to u8 pointer. In the issue, we develop a PoC to show...
