Override file_system_tile widget

[eugenz3rr]

Hi :) I love your package!
I'm using your package in a bit of a custom way. I've implemented a custom folder structure that if viewed in the filesystem three you can only see folders with hashes as names.

Can you impement a way so I can override the filesystem_list_tile.dart in filesystem_list.dart?

Cheers!;

This is in the plans for the next version, but at the moment I don't have much time to work on the package, so I can't promise a quick implementation.
