Eet: add diffeet a tool for diffing eet files.

This is not perfect at the moment, as the decoded output might change
drastically in some cases, however this is still useful for the other cases.

Anyway, we should fix the eet decoding to have a consistent order, so this
will be more useful.

@feature.
