[Rivet] Binning mismatch [Re: Bug in H1_2000_S4129130?]

[Andy Buckley]

Eike is right: LWH requires consecutive bins, so to make plots like this
where the ref data has gaps the gap removal script needs to be used on
the Rivet output. However, the script name has now changed to a more
standard form, since it is now installed in $prefix/bin by the HEAD
version: the new name is rivet-rmgaps
