Remove assert from pv beamline peak.
This MR removes an assert assert(rising == false);
that was in algorithm pv beamline peak.
This assert was raising running with option file https://gitlab.cern.ch/lhcb/Moore/-/blob/kmattiol_SMOG2/Hlt/Hlt1Conf/options/hlt1_smog_example.py under a stack compiled with x86_64_v3-centos7-clang12-dbg
.
The logic preceding the assert seemingly does not require that rising
is false, to be confirmed by @freiss .
