This change introduces a new function, process_prequantized_params, which allows loading pre-quantized parameters (e.g., from Orbax checkpoints) into a Qwix PTQ model. The function takes a tree of pre-quantized parameters and an abstract PTQ model to reconstruct the necessary `WithAux` structures, handling sharding and validating the payload format. New tests are added to cover various scenarios, including sharded Einsum layers and asymmetric quantization. PiperOrigin-RevId: 890230892
