Draft: Reduce SMOG2 sprucing bandwidth

This MR significantly reduces the bandwidth used by the SMOG2 sprucing lines.

The SMOG2 sprucing lines that are currently merged all have persistreco = True. To reduce bandwidth, many of the sprucing lines are now changed to the selective persistency model with persistreco = False. Lines that are kept persistreco = True are prescaled, with the exception of some groups of lines (dimuon and omega) that have extremely low rates and therefore very small bandwidth.
