This provides a Rust integration for the Tracy profiling library (https://bitbucket.org/wolfpld/tracy).

1. Clone the Tracy library from the above URL.
2. Follow the steps to build the profiler GUI (e.g. in tracy/profiler/build/unix/).
3. Follow the steps to build the profiler shared library (e.g. in tracy/library/unix).
4. Add this crate to your project dependencies, with the 'enable_profiler' cargo feature.
5. Call tracy_rs::load at the start of your application, providing path to library from (3).
6. Insert the main frame marker tracy_frame_marker!(); at the end of your frame.
7. Optionally, add sub-frame markers with tracy_begin_frame!() and tracy_end_frame!().
8. Annotate functions to be profiled with profile_scope!().
9. Run the application and profiler GUI.
