dstarparse: Build a tgba_digraph instead of tgba_explicit_number.

* src/dstarparse/dstarparse.yy, src/dstarparse/public.hh: Adjust the
parser to build a tgba_digraph.
* src/dstarparse/dra2ba.cc, src/dstarparse/nra2nba.cc,
src/dstarparse/nsa2tgba.cc: Temporarily adjust these functions to the
new type until they are rewritten.
