exprof

The `profile` macro wraps code blocks for easy profiling, as shown in the README example with `profile do: :timer.sleep 2000`, reducing boilerplate and setup time.

Leverages Erlang's built-in eprof profiler for accurate performance measurements, ensuring reliability and compatibility with Elixir's Erlang foundation.

Prints profiling results in a formatted table with function calls, percentages, and microseconds per call, making it straightforward to identify slow functions, as demonstrated in the sample output.

Can be integrated as a custom Mix task for profiling within build workflows, allowing automation and seamless use in development pipelines, per the README example.
