semi-global `parasail_sg_dx` not reporting `beg_ref` correctly

[nh13]

Example query GAAT and database/target AGAATA. The returned cigar via parasail_result_get_cigar is beg_query=0, beg_ref=0. The ends are fine (from the result) end_query=3, and end_ref=4. I would expect the following alignment:

q:  GAAT
    ||||
t: AGAATA

so I think the beg_ref should be 1 not 0. I am using v2.6.
