Record code coverage traces in rust to the dragondance format.
```rust use dragondance::{Module, Trace};
// Create a Trace with module info let modules = [Module::new("abcd", 0x1000, 0x2000), Module::new("libc.so", 0x555000, 0x556000)]; let mut trace = Trace::new(&modules);
// Add coverage events from your emulator, debugger, etc. trace.add(0x1204, 3); trace.add(0x1207, 12);
// Write the coverage to a dragondance coverage file trace.save("trace.dd").unwrap(); ```
