ppm_decode

PPM decoding for embedded hal , no_std rust

Example

Typically PPM input might be received via an input pin interrupt. The important thing is that you provide this parser with the time of the start of a pulse. In PPM the only time difference that matters is the difference between consecutive pulses.

```rust let mut parser = PpmParser::new();
let mut cur_time: PpmTime = 100;

loop {
    parser.handle_pulse_start(cur_time);    
    if let Some(frame) = parser.next_frame() {
        //TODO process the frame
    }

    cur_time += 100; //TODO get from clock, interrupt, or whatever
}

```
