Support for hardware without file systems

[Coderitter-GmbH]

There is already an example how to run a model, without a file system. My suggestion is, that with an additional flag, the file system supporting functions can be disabled, which makes porting easier, because there is no need to mock it.

Fair request. I kind of ran into this when trying to use cONNXr with Arduino Is that the example you are referring to?
