Autosave: investigate whether autosave can be split up within IOCs

It would be helpful to be able to have separate autosave files for different axes/sensors on various IOCs. This would be a more general solution to the problem addressed in https://github.com/ISISComputingGroup/IBEX/issues/2831.

The IOCs which stand out as particularly relevant for this are the ones which define a variable number of DB records, such as:
- Galil axes
- Eurotherm sensors
- Mk3 choppers
- Genesys
- Danfysik

This ticket should investigate whether this is possible and document the mechanism to do it. If it is possible, a new ticket should be created to do this on all the relevant IOCs.

Inizia con l’issue 2831 e verifica come autosave viene attualmente applicato agli IOCs con record variabili elencati qui: Galil axes, Eurotherm sensors, Mk3 choppers, Genesys e Danfysik. Documenta se sono possibili file autosave separati per ciascun asse o sensore; in caso affermativo, crea un ticket di follow-up che copra tutti gli IOCs pertinenti.
