Unsound usages of unsafe implementation about c_void

[llooFlashooll]

Hi, I am scanning this crate in the latest version using my own static analyzer tool.

Unsafe pointer conversion is found at:

unsafe fn output_from_raw(
        pointer: NonNull<c_void>,
        _sample_count: u32,
    ) -> Self::OutputPortType {
        Cell::from_mut(&mut *(pointer.as_ptr() as *mut f32))
    }

This unsound implementation would create memory issues such as overflow, underflow, or misalignment. The attacker can manipulate the argument pointer associated with the c_void pointer with an unexpected type, size, or alignment, which can lead to an out-of-bounds memory access bug. The c_void pointer is directly cast to *mut f32 and dereferenced, which can further corrupt the C/C++ code.

This would cause undefined behaviors in Rust. Adversaries can manipulate the associated pointer argument to cause memory safety bugs. I am reporting this issue for your attention.
