Description

When I implemented run time repacking, I required the tensor to be 2D to be eligible for repacking, I guess to simplify the code. But I forgot about MoE models, where expert weights are in 3D tensors.

This PR fixes that. This leads to very significant performance gains. E.g., for DeepSeek-Lite quantized with IQ4_XS, we get PP-512 = 545 t/s on the main branch, and PP-512 = 677 t/s with this PR when using run time repacking.
