Allows to entirely remove them from SCDliuqe

- for a single algorithm, for shot -1

- parameters
- wavegens still to come

- distinction between server AND shot
- final check for MARTe side par names duplication

- tested in hybrid em. as  accelerated reference subsystem,
it took tunable taus

issuing a warning

on all shots with SCD data,
standard channels loading still to be integrated

loading checked on nodes 02 and 03,
new hybrid params on rtcalgo tree on scd.epfl.ch
The parameter missing is FIR gain, for
which IT should provide a working MDS
node for the -1
