Backup the installed firmware to the SD card.

I apologize for the possibly confusing explanation - I'm not a professional.

Is it possible to make it so that after installing the selected firmware from the m5launcher, I can make a backup of it on the memory card (along with all the settings) and then, if necessary, install this backup back from SD?

Some firmware don't save their settings to a file (for example, meshcore), and you have to reconfigure them every time you change the firmware.

I made a workaround for this meshcore problem, it is available on Beta, to attach the data backup to a file that doesn't have the partition table in it...

Even when it doesn't attach the file, the backup is saved on the "bkp" folder, so you can rename and restore it whenever you need
