Cleanup softMuon b-tagger
Added schema configuration and flip tag configuration for the soft muon tagger.
The schema configuration is the most important part of this. In general we won't support the old b-tagging track decoration schema in reconstruction. I suspect that the only reason our derivation tests have passed so far is that we're running track augmenters in FTAG1 and FTAG2, and these follow the old convention. Since in the future we'll run the "new" convention within the AODFix we should make sure we can configure this.
Might be of interest to @rateixei.
