Improve [AnalysisTimingATLASpix]

See merge request !110

AnalysisTimingATLASpix: reordered some histograms so they are next to each other in root file, also unified names to camelCase

AnalysisTimingATLASpix: renamed hTotVsTime_low into hTotVsTime as it's filled with all ToTs, not only low

Update README eventloadereudaq2

See merge request corryvreckan/corryvreckan!109

EventLoaderEUDAQ2: update README, improved module description, in particular pointing out the naming scheme for planes: <type>_<number>

AnalysisTimingATLASpix: Improved reading of correction files and graphs, now we throw a proper error if they don't exist. Also, we're not using a pointer to the TFile object anymore such that we don't need to delete it by hand.

AnalysisTimingATLASpix: cleaned up function correctClusterTimestamp (there were still some useless old code lines + outdated comments)

Merge AnalysisTimingATLASpix module

See merge request corryvreckan/corryvreckan!105

AnalysisTimingATLASpix: removed unnecessary lines from correctClusterTimestamp as all that is performed in the [Clustering4D] module before. Only the cluster timestamp shall be updated (rest was not changing anything anyway).

AnalysisTimingATLASpix.cpp: changed tot to charge where appropriate (whenever cluster is used and not pixel)

AnalysisTimingATLASpix.h: changed tot to charge where appropriate (whenever cluster is used and not pixel)

Changing Pixel object: renaming "tot" to "value"

See merge request corryvreckan/corryvreckan!99

AnalysisTimingATLASpix: updated CMakeLists.txt -> now restricted to correct detector type (was all DUTs)

Contribution guideline points to old corry repository

See merge request corryvreckan/corryvreckan!108

Merge AnalysisEfficiency

See merge request corryvreckan/corryvreckan!106

Clustering4D: removed if(pixel charge = 0) continue because I'm convinced we don't need it (tested functionality of epsilon in a dummy project separately)

AnalysisEfficiency: changed range of hPixelEfficiency such that it goes from 0 to 1.005 (100% = bin from 1.0 to 1.005)

Had to merge master once more to get latest correction changes (my cherry-pick action was completely useless).
