h264-profile-level-id

Idiomatic Rust port of https://github.com/ibc/h264-profile-level-id by Iñaki Baz Castillo.

Rust utility to process H264 profile-level-id values based on Google's libwebrtc C++ code.

Basic usage example:

```rust use h264profilelevel_id::{Profile, Level, ProfileLevelId};

fn main () { let profilelevelid: ProfileLevelId = "42e01f".parse().unwrap();

assert_eq!(profile_level_id.profile(), Profile::ConstrainedBaseline);
assert_eq!(profile_level_id.level(), Level::Level31);

let s = profile_level_id.to_string();

assert_eq!(s.as_str(), "42e01f");

let local_profile_level_id = "42e01f".parse::<ProfileLevelId>().ok();
let local_level_asymmetry_allowed = true;

let remote_profile_level_id = "42e015".parse::<ProfileLevelId>().ok();
let remote_level_asymmetry_allowed = true;

assert_eq!(
    h264_profile_level_id::generate_profile_level_id_for_answer(
        local_profile_level_id,
        local_level_asymmetry_allowed,
        remote_profile_level_id,
        remote_level_asymmetry_allowed
    ),
    Ok("42e01f".parse::<ProfileLevelId>().unwrap()),
);

} ```
