Simple timings profiler
### Example
```rust
fn main() -> std::io::Result<()> {
profl::init("timings.data");
let mut total = 0;
for i in 0..1000 {
total += profl::span!("some_ctx", {
// long operation
std::thread::sleep(std::time::Duration::from_millis(i % 40));
i
});
}
Ok(())
}
```
### Processing results:
```bash
profl --path timings.data
```
#### Rendered metrics (`plot.svg`)
#### Output:
