Ray Smith 85958f5fd3 Added MatPtr/MatPtrT/MatStorageT/MatStorage as a dynamically-sized replacement for CompressedArray. 
Definition of array size is moved to the constructor.
Allocation is separate and parallelized.
All users of weights_raw.h migrated to CompressedWeights and weights_raw.h deleted.
Replaced all previous ForEachTensor functions with a single unified function.

Daniel Keysers f8835fe4a4 Add support for PaliGemma Vision-LM (224x224) to gemma.cpp 
See https://arxiv.org/abs/2407.07726 for a description of the model.
Because PaliGemma operates as a prefix-LM on the image+prompt, add support for that.
