Reduce the OptoHybrid temperature limits
For operations at p5, the default temperature limits have been reduced as follow:
- Over-temperature trigger (triggers the automatic power off) - 65°C
- Over-temperature reset (restarts the FPGA) - 55°C
- Temperature-sensore alarm trigger - 55°C
- Temperature-sensore alarm reset - 55°C
Additionally, ensure that the slow-control counters are only incremented when the alarm is raised, not for every clock cycle (i.e. added a oneshot).
