#931 closed defect (fixed)

incorrect parsing of lt_idx_sps if num_long_term_ref_pics_sps == 1

Description

According to the spec, if num_long_term_ref_pics_sps == 1, parsing lt_idx_sps should consume Ceil( Log2( 1 ) ) = 0 bits.
In HM, lt_idx_sps consumes 1 bit if num_long_term_ref_pics_sps == 1.

        Int bitsForLtrpInSPS = 1;
        while (rpcSlice->getSPS()->getNumLongTermRefPicSPS() > (1 << bitsForLtrpInSPS))
        {
          bitsForLtrpInSPS++;
        }

Parsing of lt_idx_sps should probably use code equivalent to that for parsing short_term_ref_pic_set_idx.
