FTagAnalysisAlgorithms declare BTaggingInformationDecoratorAlg as component

CP::BTaggingInformationDecoratorAlg is required for continuous b-tagging, but the algorithm was never declared. Running FTagAnalysisAlgorithms with a continuous working point would attempt to load this algorithm and fail. Updated FTagAnalysisAlgorithms_entries.cxx to declare it, and tests ran fine.

I think this got through because the test setup (python/FTagAnalysisAlgorithmsTest.py) only runs the 77% WP. Updated this file to run both a single fixed-cut WP and the continuous WP (also switched to the newer DL1dv01 tagger), and it runs fine on the ASG test files.
