Example, that's fresh on my mind. Doesn't even include the enum dance (TryFromPrimitive etc)

```rust
#[derive(Debug)]
struct LocationData {
    pub status: Status,
    pub direction: u8,
    pub speed_horizontal: u8,
    pub speed_vertical: i8,
    // ...
}

impl LocationData {
    pub fn from_bytes(bytes: &[u8]) -> Self {
        Self {
            status: Status::Ground, // todo
            direction: bytes[2],
            speed_horizontal: bytes[3],
            speed_vertical: bytes[4].into(),
            latitude: i32::from_le_bytes(bytes[5..9].try_into().unwrap()),
            longitude: i32::from_le_bytes(bytes[9..13].try_into().unwrap()),
            alt_baro: u16::from_le_bytes(bytes[13..15].try_into().unwrap()),
            alt_geo: u16::from_le_bytes(bytes[15..17].try_into().unwrap()),
```
