A lightweight parser for [logfmt](https://brandur.org/logfmt).
```rust
use logfmt::Logfmt;
let line = r#"level=info msg="request completed" duration=42ms"#;
for (key, value) in line.logfmt() {
}
```
Logfmt is a logging format that encodes data as space-separated key-value pairs:
```
level=info msg="hello world" count=42
```
It's human-readable, easy to parse, and widely used in logging.
