CbmTaskBuildRawEvents: Implemented a simple seed finder which takes digi timestamps from a given list of detectors and compiles them into a sorted list of seed times. Works as input for CbmAlgoBuildRawEvents.

CbmAlgoBuildRawEvents: Cleanup. Eliminated distinction between T0 and other detectors in CheckTriggerConditions().

Fixed time window size and minimum digi number cut for 2018 event builder in /macro/run/run_reco.C. All event builders now produce reasonable QA results.

CbmBuildEventsQA: Now obtains fraction of total digis (per detector) which were correctly assigned to events.

CbmBuildEventsQA: Instead of a single detector a list of reference detectors can now be used to match raw events to MC events.

CbmBuildEventsQA: Applied patch by P.-A. Loizeau to catch events with no digis of reference detector.

Fixed an issue whereby CbmBuildEventsQA was unable to deal with digi matches without links (noise). Added CbmBuildEventsQA to /macro/run/run_reco.C.

Updated interface of CbmBuildEventsQA class. Digis now fetched from DigiManager instead of FairRootManager.

Changed STS seed window size and minimum seed digi number for raw event builder in /macro/run/run_reco.C.

Renamed Cbm2021EventBuilder to CbmBuildRawEvents. Solved naming conflicts of utility classes (removed dependency on 2019 version).

Cbm2021EventBuilder: Applied formatting. Added new classes to CbmEventBuilderLinkDef and CMakeLists. Including EOverlapMode and EventBuilderDetector from 2019 event builder for now to avoid name clash. Added option to call 2021 event builder to macro/run/run_reco.C.

Update parameters hash to  fixed trd verison see (CbmSoft/cbmroot_parameter!32)[MR32!]

The function Cbm::File::IsRootFile checks if a file with the given name
exists and if this is confirmed it checks if the file is either a ROOT
file or a ROOT file stored in a ZIP file. ROOT is able to handle ROOT
files stored in a ZIP archive.
The function returns true when the file is a ROOT file  and false in
any other case.

Since the size of a single PLUTO file is very small the preferred storage
solution for them is to store a large number of them in a archive.
ROOT is able to handle ROOT files stored in a ZIP archive so the file
handling in the class was adapted for the ZIP file usage.

Newer FairSoft and FairRoot versions are compiled with the C++17 standard
Pass this information properly to the build system of the AnalysisTreeQA
package.

Add also some more new parameters.
Some hopefully minor changes.

The include statements are ordered from local to global with allways a blank
line between the blocks.

Add gDirectory protection in any case even if directory is not changed.
For some files gFile an gDirectory where only set back if file was opened.
Restore the original values in any case ebven if not necessary.

Properly install AnalysisTreeQA.
Install missing pluto header file. Closes #2006 @1h
