* gguf-py : fix some metadata name extraction edge cases * convert_lora : use the lora dir for the model card path * gguf-py : more metadata edge cases fixes Multiple finetune versions are now joined together, and the removal of the basename annotation on trailing versions is more robust. * gguf-py : add more name metadata extraction tests * convert_lora : fix default filename The default filename was previously hardcoded. * convert_hf : Model.fname_out can no longer be None * gguf-py : do not use title case for naming convention Some models use acronyms in lowercase, which can't be title-cased like other words, so it's best to simply use the same case as in the original model name. Note that the size label still has an uppercased suffix to make it distinguishable from the context size of a finetune.
