The following example shows off reading from ADS-B bytes from a demodulation server into our Frame
struct and then executing the fmt::Display Trait for display of information.
use hexlit::hex;
use adsb_deku::Frame;
let bytes = hex!("8da2c1bd587ba2adb31799cb802b");
let frame = Frame::from_bytes(&bytes).unwrap();

For testing this library, you can run our app 1090 with the following options for exiting program
on missing fmt::Display or bytes protocol decode.
> cd ../apps
> cargo r --release --bin 1090 -- --debug --disable-airplanes --panic-decode --panic-display
This library is also fuzzed, ensuring no panic when parsing from demodulated bytes.
> cargo fuzz run fuzz_target_1
> cargo +nightly fmt
Benchmarking is done against a file containing 215606 ADS-B messages: lax-messages.txt.
Quick math (215606 / 692.80) says the average speed of decoding is ~311.21 ms a message.
A ~3% speedup can be gained on some systems by using RUSTFLAGS="-C target-cpu=native"
