Q2_0

Please also add q2_0 quants. Since your model says it was trained for 128 groups size, and the tq*_0 quants are 256, they would be lossy and of lower quality, as 2 group scales will be combined. q2_0 has a group size of 64, so there would be 2 group scales the same, but losslessly. (also better cuda support)

There is ongoing testing in https://github.com/ggml-org/llama.cpp/pull/27000 .

Did you experiment with quantizing the embeddings? Because they are a large chunk and seem to quant well.
