Add the ability to refocus during sequences

[Alistair M]

Just like how in a sequence there's the ability to dither every N frames, there should also be the ability to use a motorized focuser to refocus every N frames, or maybe the ability to trigger it when the temperature changes by X degrees, if the focuser has a temperature sensor.

This feature is planned. I can already implement it, but only using simulators which could cause issues. Once I have a motorized focuser I will definitely do it.

Current available options: - Autofocus on startup - Autofocus on filter change

The options to autofocus after temp shift and after x frames will be added later.

[Stefan B]

existing triggers: on start on filter change

new triggers will be added in next version: after # of exposures after x minutes after x degrees of temperature change (focuser has to report temperature for this to work)
