Integrated Pipeline: refactored logging end-to-end tests, now use an extra log appender to a ByteArrayOutputStream

-default configuration loading now offers a variant to specify desired verbosity

Integrated Pipeline: splitted ResultWriterEvent matchers into several objects to avoid property name clashes with finer-grained imports

Integrated Pipeline: splitted CalculationParserEvent matchers into several objects to avoid property name clashes with finer-grained imports

Integrated Pipeline: splitted TreeParserEvent matchers into several objects to avoid property name clashes with finer-grained imports

Integrated Pipeline: ParsingTaskGenerators now forward scanning errors to the TreeParser and its EventListener

Integrated Pipeline: prepared TreeParser implementations to be able to process errors properly, updated existing tests

Integrated Pipeline: ParsingResultsProcessingManager has correct output path and failure count in outgoing messages/events

Integrated Pipeline: single-calculation json writer can be queried for the result output location for a file tree

Integrated Pipeline: single-calculation HDF5 writer can be queried for the result output location for a file tree

Integrated Pipeline: merged HDF5 writer can be queried for the result output location for a file tree

Integrated Pipeline: FileTreeScanTasks now require Zip-archives to have a well-defined rawdata archive name

Integrated Pipeline: added EventListener registration and start tree event notifications to ParsingResultsProcessingManager

Integrated Pipeline: added missing test data constructors for CalculationParserEvents and added them to tests

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

Integrated Pipeline: adjusted worker counts in end-to-end tests to have more/equally many/less workers than tasks

Integrated Pipeline: renamed TreeParserProcessEvent to TreeParserEvent, moved matcher construction helpers to a separate object
