Fixes #22.

I just tried to write a test using a symlinked file or directory (to make sure .resolve() works), but apparently .resolve() is not necessary, as it works either way (at least on linux) :shrug:

Another thought: we should probably use .expanduser() in Edf.write() as well

No idea what this actually does, it probably doesn't hurt to leave it in. But it's up to you, let me know if you want me to remove it.

I'll add it to Edf.write(), sure.

(I didn't mean to put my last comment in a review. I meant to write a normal comment, but the UI from within VS Code is... not ideal.)
