feature request: play a default fseq file when no FPP sync traffic is coming

[dutch-anykey]

Feature request:

I built 20 hardware controllers based on the devc esp32 kit with SD connected. These are going to be used on led-suits. (We as a friends group participate in a local carnaval light parade)
The plan is to use them in “FPP remote” mode so each controller plays its own fseq from SD card and sync via wifi.
However I anticipate that sometimes people walk out of range of the wifi coverage. For that it would be great if it starts playing a “default” fseq file on the SD card.

Feature request:
Is it possible to detect if no FPP sync messages are coming in for x seconds and then start playing a default fseq file on the sd card?
I.e. primary input will be disabled, secondary input: FPP Remote. Ad an option under FPP remote configuration like “on idle play default.fseq”
And of course when FPP sync starts again to continue playing FPP remote mode.
