More system tests

• Fix newly introduced bug with the changes to the report summary being printed to stdout instead of stderr The change breaks piping from e.g. a fastpasta filtering and piping to another fastpasta that is checking like: fastpasta --filter-link 8 10_rdh.raw | fastpasta check sanity because the report summary also gets piped. Fixed it by not printing the report when DataOutputMode is Stdout.

Add test for piping to/from fastpast, found bug recently introduced, fixed it. Add tests for the rest of test files that were only tested in the bash script.
