Combine v9

This version is targeting CMSSW_11_3_4 but is broadly compatible with ROOT 6.22 through ROOT 6.26, and hence also CMSSW 12_X release series. Installation instructions are summarized in https://cms-analysis.github.io/HiggsAnalysis-CombinedLimit/#installation-instructions

New features include:

• Full python3 compatibility (#759)
• Improved ROOT version support (#776)
• 2D RooParametricHist class (#545)
• Shapes from pandas dataframe (#548)
• Added instructions and tools for producing inputs for simplified likelihoods (#800)
• Many bug fixes (see e.g. list of merged PRs to 112x)

From this point on, new developments should always target the main branch, with backports to release series as necessary.
