Add Event Architecture

[aellul27]

Implement a high-level architecture for OpenCanoe timing software to unifies inputs from multiple timers (TIMY, Theoretical Timer, ALGE, etc.) and standardizes their outputs into an event stream.

Components:

• IO Layer (IO Factory / Device Drivers / Protocol Handlers / Connection Manager)

Abstracts hardware protocols (RS232, TCP, USB, etc.)

Supports multiple devices and protocols

Allows mocking for tests

• Parser Layer (Timer Parsers)

Converts raw timer data into the TimingEvent type

• Event Stream

Single unified output stream of all TimingEvents

User API:

let mut system = TimingSystem::new();

for device in system.discover_devices() {

    println!("{}", device.name());

}

system.connect_device(device);

let mut events = system.events();

while let Some(event) = events.next().await {

    match event {

        TimingEvent::RaceEvent(e) => {}

        TimingEvent::DeviceConnected(id) => {}

        TimingEvent::DeviceError(e) => {}

        _ => {}

    }
