This PR fixes in issue that could arise in Firefox when running the Peptonizer on a large sample. If too many workers are started in parallel (each consuming quite a lot of memory), the total required memory is more than what Firefox exposes to a web app, causing it to crash.
This PR fixes this issue by only using 6 parallel workers for the peptonizer when the current browser is Firefox. The parallellisation for Chromium-based browsers (8 workers) and Safari (2 workers) remain the same.
