Bitrise step takes twice as long to process xcode files as opposed to the raw setup

Description

Copying this over from `3.1.2` fails to find Xcode coverage files · Issue #16 · codecov/codecov-bitrise · GitHub

The only issue I have with it is the processing time.
First I thought it just stuck on on ‘Running xcode coversion’ step.

However, when I added -v (verbose) flag into other flags, I found it did go through each source file to convert.
It took an extra 16 minutes to convert all files and create a coverage .json file.

If I do it via solution from here it takes 8 minutes only.

Is there any way to optimize this conversion process?
