Helper Method to Re-Format Internal Flash Drives on Boards that Support It

[gligorov]

Description

At present there is no way to reformat the internal flash on devices. If for any reason, format is needed, ( security, troubleshooting etc.), there is no way to do that.

How to solve the problem

Add a simple helper method like Format(string driveLetter) or something similar to be used from a library that is best suited for this.

You can already do this by getting all the files and deleting all of them. Wouldn't that be enough?
It's especially easy on an internal storage as no folder is supported. But it will just work the same way with a recurring function.

Nope. This requires a native call in order to restart/format the file system or SPIFFs. When it comes to this, it's because the file system got unusable.

[torbacz]

Maybe command with nanoff will be sufficient?

@josesimoes should this be closed now?

The linked PR has added support for this only for SPIFFs storage. I think it should be extended to the other supported storage: SD Cards and USB MSD. That's why I left it open.
