Has not been declared

I had to add these two lines to LFSInterface.h to make it work

#include <Arduino.h>
#include <lfs.h>

Is that an issue on my side? How did you make it work without them.
I kept getting a lot of undeclared errors on the type byte and for the whole struct.

Hmm. I've tested this with an older version of Arduino several years ago, and I know that newer versions break the resolution of headers sometimes. I'll add this in and update my Arduino version to test.
