Possible corrupt SPIFFS

[Gandalf1783]

In dualETH.ino line 116 following theres no way to reset the SPIFFS via any command.

Also, in line 122 (I believe) you check if file /formatted.txt exists and if it does you format the SPIFFS and re-create the file?!

It would be nice if there could be an option (either via UDP/TCP or a web endpoint) to reset, and force format the SPIFFS to get a working, clean config.

E.g. my Node does not boot up, I suppose due to config errors.
However, I will raise that one again somewhere else in a different issue.
