Method is_pos_2d

subprojects/llama.cpp/src/llama-batch.h:25–28

typical for M-RoPE cases: 0 - sequantial position of the tokens/embeddings in the sequence 1 - y position in the image 2 - x position in the image 3 - other

    //   2 - x position in the image
    //   3 - other
    bool is_pos_2d() const {
        // TODO @ngxson : we may need to check for model arch when more models use >1 positions
        return n_pos >= 3;
    }

    uint32_t b_equal_seqs; // note: this is a boolean, but we use an int32_t for alignment
                           //       otherwise address sanitizer complains
