Field-handler should receive field-diffs, not the object-diffs

Expected Behavior

The field-handler (@kopf.on.field) receives the diff object with the diffs specific for that field, same as the old & new values. And the field paths should be relative to the handled field.

Actual Behavior

The diff object contains the diffs for the whole object (all fields), and relative to the object's root.

Detected while writing the documentation (though was marked with a TODO in the source code).
