Get rid of leaf_data_binary_data
I added a new parser "adapter" that creates ad-hoc x3::rule parser which
can coerce attributes to whatever I want. Before this, I had to
explicitly create x3::rule myself. This will shave off some lines and
will hopefully be useful in more places (my next target is
leaf_data_identityRef_data).
