Call geterr() to return FileSystem error strings #10

Closed adamsoutar closed 2 years ago

adamsoutar commented 2 years ago

When a FileSystem call errors on Playdate, we can call geterr() to get a reason string for the failure.

This PR returns that reason within the errors from the FileSystem struct, so instead of just "Error -1", you can log something more like:

(it also fixes a small typo where errors in seek would say Error from write)

I hope this is helpful. Do let me know if there's something wrong with the code, like if it's not in your preferred style :)
