Update mass windows of B2JpsiX0

Maximilien Chefdeville requested to merge chefdevi_stripping_branch into 2018-patches

Inlarge mass window of eta[pipigamma] to accommodate for part-reco eta[pipipi0] when one photon is missed.

Increased rate compensated by reducing mass window of etap[etapipi] from +/-150 to +/-100 MeV/c2.

Rate test on 10k event (still) show 0 events for the 2 updated lines.
