Replacing PR#5954: Threadsafe faster hcal25ns reco method2

 A new PR. This is the SAME as the latest update of the PR#5954 and meant to replace that (with a fresh pull request...)

(ref: PR#5954: https://github.com/cms-sw/cmssw/pull/5954)
This was done when I mistook that method I was default. Since now method II is default, I don't think we need this one anymore. I will remove this and add a HBHE_custom_Method1.py and the essential configuration line is the same.
