`fpm diff`
`fpm diff` shows the changes in the package, compared with what was last synced using `fpm sync`.

Developer Notes
We use diffy to create diff:
```diffy::create_patch(original, modified)
```
Note that this creates a diff which is slightly incompatible with `git diff` output, so we cant use `elm-diff` for example.
