-trait-import on the suite level was causing name clashes between message and event matchers

Integrated Pipeline: added a short sleep to mock processing in CalculationParsingFlowSpec to stabilize task distribution

Integrated Pipeline: moved path/treetype validation logic from Graph element to CalculationParsingEngine

Integrated Pipeline: refactored CalculationParsingFlow tests, added stream assertion for normal completion

Integrated Pipeline: merged parsing task/result messages into a single file to merge the start/end signals

-parsing and result signals now use the same start/end signal case classes to get rid of duplicate code
 and unnecessary transformations

-CalculationParsingFlow now uses the extractedPath field assigned by the ArchiveUnpackingFlow
-removed some tests for CalculationParsingFlow that are no longer needed

Integrated Pipeline: CalculationParsingFlow test fixture inherits from StreamAssertions, renamed test sink/source

Integrated Pipeline: tree-type validation moved from CalculationParsingEngine to CalculationParsingFlow

-now also supports zip-archives

Integrated Pipeline: CalculationParsingFlow now specifies the path to the main file for extracted zip-archive files

Integrated Pipeline: path to main file is now determined by CalculationParsingFlow and passed down from there

Integrated Pipeline: CalculationParsingFlow cleans up temporary extracted files when receiving end tree signal

Integrated Pipeline: CalculationParsingFlow extracts to be processed rawdata archives to a temporary directory

-intended to be used with with a RAMdisk filesystem in production, thus the entire archive (at most 30 GB)
 is extracted once and shared by all workers instead of extracting worker-private copies of the required
 file-trees

Integrated Pipeline: CalculationParsingFlow now validates that no parsing requests arive after the tree end signal

Integrated Pipeline: CalculationParsngFlow now validates that the tree start signal arrives before the parsing requests

-CalculationParsingFlow now sends tree start/end signals to its outlet instead of discarding them
-ParsingResultsProcessorFlow silently discards incoming tree start/end signals

Integrated Pipeline: FileParsingTask contains the original FileTreeScanTask as field rather than copying all values

Integrated Pipeline: FileParsingResults contains the original FileParsingTask as field rather than copying all values

-will be extended later to have multiple workers internally
