This function is really inefficient: `Plane::as_data_flatten`

[LetsMelon]

rusvid/crates/core/src/plane.rs

Line 165 in 768ced3

pub fn as_data_flatten(&self) -> Vec<u8> {

I think it would be a good idea to replace the current function body with

let total_len = self.data.len() * 4;
let mut result = Vec::with_capacity(total_len);

for p in &self.data {
  result.extend_from_slice(&p.to_raw());
}

result

, but before that the two versions must be bench marked.
