   - added equipment-*.dropPagesWithError: if set, the pages with RDH errors are discarded (requires rdhCheckEnabled or rdhUseFirstInPage). This may be used if downstream software is not robust to RDH errors.
 - Disabled unused RDMA features (still available by switch in CMake)
 - Added feature for memory banks real time monitoring. Enabled by setting membanksMonitorRate in /etc/o2.d/readout-defaults.cfg. Output (high-rate text) can be seen locally in real time with `tail -f /tmp/readout-monitor-mempool-(id)`. The status of each page in the bank is displayed.

+- Updated naming of files saved to disk when equipment-*.saveErrorPagesMax is set. Now includes timestamp, equipment id, and file counter: e.g. /tmp/readout-t1678288819-eq1-superpage.1.raw
