Btw, there is some great stuff here regarding encdec, repr(c), and packetstruct, but this is also a bandaid for a specific pain point:
```rust
/// Syntax helper for parsing multi-byte fields into primitives.
///
/// Example: `parse_le!!(bytes, i32, 5..9);`
#[macro_export]
macro_rules! parse_le {
    ($bytes:expr, $t:ty, $range:expr) => {{
        <$t>::from_le_bytes($bytes[$range].try_into().unwrap())
    }};
}
```
