Python 3.6 issue with groups

@vwyu @bunnyamin thank you the report and the detailed description. Hopefully the bug is fixed on the latest master. Could you verify?

I just downloaded the module, and am having the same problem.

I am not familiar with the output of module re.sre_parse, however, the following seems to remedy the problem for at least i[0] == sre_parse.SUBPATTERN.

line 209      ret = ggen(ret, _gen, i[1][
line 210 -                1], limit=limit, count=False, grouprefs=grouprefs, groupref=i[1][0])
line 210 +                3], limit=limit, count=False, grouprefs=grouprefs, groupref=i[1][0])

Line 208 should probably also change the index key from i[1][1] to i[1][3].

EDIT: i[0] == sre_parse.ASSERT fails; i[1] = (1, [(LITERAL, 120)]).
Changed to x = i[1][1] if i[0] == sre_parse.ASSERT else i[1][3], however, tests.py

    exrex.getone('(a|(b|(c|d)))', 11) -> 'd'

    exrex.generate('(a|(b|(c|d)))', 11)) ->
        'a'
        'b'
        'c'
        'd'
