// usage:
//  ./update models/llama/ggml-model-input.bin models/llama/ggml-model-output.bin
// The intent of this executable is to open old model formats and save them in the most recent format.
// Updating a model in ggml/ggmf format to ggjt will results in much faster load times as mmap can be used to map the model to the address space directly.
// This will maintain ftype (f16, f32, q4_[n], etc)
// Also, if modified locally (along with llama.cpp), you can use this to add or remove hparams, score, etc from a model. For instance, I used this to open a model in ggjt (no score) and saved it again as ggjt (with score).
