Reporting branch coverage percentage in the terminal output about simplecov

[noahfpf]

This appears to be a limitation in simplecov-html, the default formatter:
https://github.com/simplecov-ruby/simplecov-html/blob/22470072b687c60d11f488a5b86e239d1c7b4498/lib/simplecov-html.rb#L35

Here's a workaround:

SimpleCov.at_exit do
  SimpleCov.result.format!

  result = SimpleCov.result
  if result.total_branches&.positive?
    covered_branches_percent = 100.0 * result.covered_branches / result.total_branches
    puts "Branch coverage: #{result.covered_branches} / #{result.total_branches} branches (#{covered_branches_percent.round(2)}%) covered."
  end
end

Thanks. Shouldn't the output_message method in the formatter be adjusted to do this?
